In this episode we'll talk about a super useful feature that was introduced back in Java version 8, known as Lambdas. The Lambda feature is something you didn't know you desperately wanted or needed until you understood it. The Lambda syntax allows you to write much cleaner and more readable code, while also empowering you to get more done with less code. In this lecture, I'll be referring to some code that you can download via this github repository.

Cascading Style Sheets are a bit of a tricky beast in HTML. Given this fact, I wanted to dedicate an entire section to just this topic. Let’s start with the basics, shall we? What are Cascading Style Sheets (CSS)? Well, we’ve already talked a little bit about HTML formatting tags (like Cascading Style Sheets actually exist as a completely separate file to your HTML code. |

In this HTML tutorial I would like to introduce two concepts to you:
The DOCTYPECurrently as of the date this was published, web browsers are (mostly) supporting HTML 5. HTML has gone through several versions and variations over it’s lifetime, and because of this it’s highly suggested that you include something called a DOCTYPE. The purpose of a DOCTYPE is to tell the web browsers what version of HTML you are using on any given webpage. The benefit of telling the web-browser what version of HTML you are using is that you save it from having to “guess”, which can often lead to strange behavior. |

I’m so ridiculously excited to be introducing a whole new aspect of programming. Over the next few months I will be posting new articles on the topics of HTML, Javascript and jQuery. These are all technologies that you can use to create your very own interactive website. The really cool thing about building websites, is that you can leverage your existing knowledge of Java to create ever MORE powerful websites. But let’s not get ahead of ourselves, for now we’ll focus first on HTML, then we’ll move into Javascript/jQuery. But enough big picture talk, let’s get into our introduction to html shall we?
An Introduction to HTML…HTML stands for HyperText Markup Language, and all this really means is that HTML is not a programming language, but rather just a set of rules for structuring your text. This means that if you type out certain words in a particular way, you can create a website! Piece of cake right? For the most part, YES, it is a piece of cake |

The presentation layer is one of the three main layers in object-oriented programming. The three main layers include:
Now, these three layers are typically related to enterprise web applications. It’s a design pattern used to help separate your code out in three distinct areas that (if need be) can easily be switched out with another programming language or technology. So if you keep all of your presentation layer code in one area of your application, switching presentation layer technologies shouldn’t be too difficult. Same rules apply to the business and data layers. If you separated your code out properly, switching databases shouldn’t be too big of an issue. Having said that, we’ll be focusing on the presentation layer. The four big players (in terms of technology) in the presentation layer are as follows: |

How to Fix Duplicate Data from Hibernate QueriesThis problem was the bane of my existence when I first started using Hibernate because I had no idea where the problem was coming from. If you’re executing a query and finding that you have a bunch of duplicate records and haven’t a clue why, then you’re in the right place. You see the problem is typically caused by having left joins (or optional joins) in your objects. When you have a base object, like say Consider this scenario… A So what happens when you run a query that joins to the So because of this, Hibernate doesn’t massage the data for you, it just returns exactly what it got from the database. The ball is in your court to tell Hibernate what to do with records it has retrieved. There are two solutions to this problem:

Now it’s time to dive into the nitty gritty of Hibernate’s mysterious inner workings. I’m by no means an expert in Hibernate, but I do use it almost every day for my own projects, so I do know a thing or two about how it works. One topic that had me scratching my head for ages was the Hibernate life cycle. What I mean by the life cycle is the way Hibernate interacts with Java objects at certain points in the existence of said Java objects. Let’s start from the beginning… What the heck is a Hibernate Life Cycle?You see, Hibernate is picky about your Java objects. Hibernate prefers your objects to be in a certain “state”, known as the persistent state… this persistent state is one of four different states that exist inside of the hibernate persistence life cycle. Once you have a firm grasp of the different states that an object can be in (as it pertains to Hibernate) you’ll be well on your way to mastering the Hibernate framework. So let’s get this Hibernate persistence life cycle lesson started shall we? Continue reading via: http://howtoprogramwithjava.com/session58 |

What the heck is a Fetch Type?Great question! Hibernate is a very handy framework for removing your need to fully understand SQL, but it will force you to understand things such as joins. Joining two tables in SQL is the foundation of a relational database, as joins allow you to actually define relationships between tables (objects). Having said that, relationships are important to understand when talking about fetch types in Hibernate. This is the case because whenever you define a relationship in Hibernate, you’ll also need to define the fetch type. The fetch type essentially decides whether or not to load all of the relationships of a particular object/table as soon as the object/table is initially fetched. For more information please see the show notes via http://howtoprogramwithjava.com/session57 |

Hibernate @ManyToMany UnidirectionalThe Many-to-Many relationship can be best described by example. The example we’re going to use is that of the relationship between an Other examples of the many to many relationship are Students to Courses and Employees to Projects. Let’s take a look at how the unidirectional many-to-many relationship is created using Hibernate... for more info please visit http://howtoprogramwithjava.com/session56 |
Thu, 7 August 2014
One-to-One Unidirectional RelationshipSince you’ve already learned about the ins and outs of how unidirectional one-to-many and bidirectional one-to-many relationships work, it’s time to learn about the One-to-One relationships. We will start things off with the unidirectional One-to-One relationship and how it’s set up in Hibernate. First thing is first, you need to understand how a One-to-One relationship is actually set up in a database. Once you understand that the child table declares the parent’s primary key as the child’s primary key, then we can get moving with the Hibernate stuff! For this example, we are going to use the One-to-One relationship between an For more information, please read the show notes via http://howtoprogramwithjava.com/session55 |
Mon, 28 July 2014
Since we’ve already learned about the unidirectional @ManyToOne relationship, we can now move on to talking about what a bidirectional relationship is like, when using Hibernate. The term “bidirectional” literally means “functioning in two directions”, which is the concept that we will apply in our relationships between two Java objects. When we have a bidirectional relationship between objects, it means that we are able to access Object A from Object B, and Object B from Object A. We can apply this logic to our real world coding example that we saw in the last post. The example we will use is the relationship between an Employer and an Employee. Previously, we only defined a unidirectional relationship, so we could only access the Employer from the Employee object and not vice-versa. Now let’s take a look at how to transform our existing unidirectional relationship into a bidirectional one. |

In the past we have learned about database relationships, specifically the One-to-Many as well as the Many-to-Many and One-to-One and that was all good, great and grand… But now I want to talk about how to create those same relationships inside of Hibernate. Specifically, I want to focus on the One-to-Many relationship in Hibernate and how we go about mapping it out in our Java objects. But before we do, a word on unidirectional and bidirectional relationships. Unidirectional vs BidirectionalIn Hibernate, it’s possible to map all three relationships that are available in a standard database, these include:
But what Hibernate also includes is the ability to make EACH of those relationships either unidirectional or bidirectional. This means that we can have a unidirectional One-to-One and a bidirectional One-to-One mapping, as well as a unidirectional One-to-Many and a bidirectional One-to-Many, as well as a unidirectional Many-to-Many and a bidirectional Many-to-Many relationship. That’s a lot of relationships! So what exactly are unidirectional and bidirectional relationships? Learn more on the show notes page via http://howtoprogramwithjava.com/session53 |

Data Access Objects – What are they?Data Access Objects (or DAOs for short) are used as a direct line of connection and communication with our database. DAOs are used when the actual CRUD (CRUD = Create, Read, Update, Delete) operations are needed and invoked in our Java code. These data access objects also represent the “data layer” of our application. These objects are still just plain old Java objects that incorporate the use of some Hibernate annotations to give them the functionality we need from them. Again, that functionality being the communication with the database. Also, believe it or not, the concept of creating a file specifically for accessing the database is a design pattern. It’s called the Data Access Object Pattern and you can read more about it from this nice short Wiki article. What Hibernate Annotations Should We Use?Okay, so now that you’re somewhat familiar with DAOs, it’s time to learn how to integrate these plain old Java objects with our Hibernate framework (so they actually do the work we need them to do). There are two main annotations that you need to be familiar with:

What You’ll LearnThe focus of this podcast / blog post is to teach you how to create the connection between your Java objects and the SQL Database tables.

When I say that the goal is to communicate with your database, what I mean is:

What is a Persistence Framework? As the name implies, it has something to do with persisting things... this means that we're still talking about databases. But what is it that we are persisting with this framework? Objects (of course) A persistence framework is something we use in Java to bridge the gap between Java and SQL. Hopefully we've gone through all of my previous tutorials and have learned a thing or two about Java and SQL. But one thing I haven't taught you yet, is how to put your knowledge of SQL into Java. That's what I'll be teaching you throughout these Hibernate (persistence framework) tutorials. And if you haven't guessed it already, Hibernate is a persistence framework that you can use in Java. It's what allows you to write Java code (staying true to Object Oriented programming practices) and yet still be able to communicate with your database. Cool eh?

After having talked about all the SQL Aggregate functions, there’s one more topic that goes hand in hand with what we’ve already learned… The This particular keyword allows us to take a bunch of data and mash it all together into matching groups and then perform aggregate functions on those groups (like You might ask yourself why you’d want to “mash together” a bunch of data. The answer to this is best explained with an example, but let me try to put it in regular words before we jump into our example. Grouping data together allows us to look at aggregate data in relation to unique piece of data (or rows), a typical use case would be to group all the matching data together so you can get a count of the number of occurrences of specific data. An example related to grouping and counting could be a presidential election, you’ll have all the votes in a database and you’ll want to group that data together to get the total votes for each unique candidate...

In today’s podcast episode you’ll be learning all about the aggregate functions that exist in SQL. What the heck is an aggregate function? Well that’s what I’m going to try and teach you today, and I promise, it’s not a difficult concept to grasp. Just think of an aggregate function as a method that you’re calling that will process data in your database and return a value. Obviously the returned value will depend on which of the aggregate functions you choose to use. So that begs an obvious question, what are the aggregate functions that we can use in SQL? I’m glad you asked, here’s the ones that I use all the time in MySQL:
Okay, great! So now we know what the names of these functions are, now let’s see some examples of them in use! |

There are three categories of joins that you can make use of in SQL:
But before we dive into the categories of joins, we first need to have an understanding of what a join really is. Joins are used in SQL to bring together all the relevant data from multiple database tables. Remember that we've broken data down into multiple tables and established relationships between the tables.

In this post we will be expanding on the topic of database relationships and touch on two that are less common but just as useful. Many-to-Many RelationshipThe many-to-many database relationship is used when you are in the situation where the rows in the first table can map to multiple rows in the second table… and those rows in the second table can also map to multiple (different) rows in the first table.
One-to-One RelationshipA One-to-One relationship means that you have two tables that have a relationship, but that relationship only exists in such a way that any given row from Table A can have at most one matching row in Table B. |

We’ve talked about relational databases already, and we’ve learned why this type of database management really dovetails with the object oriented programming model. So now I want to dive into the specifics when it comes to relationships. What are the different types of relationships in SQL?There are three types of relationships you can have in SQL, they are:
In this episode we are going to be focusing on the One-to-Many relationship as it’s the most commonly used in my opinion. |

Terminology It's the foundation when learning any new concepts. In this episode of the "How to Program with Java Podcast" we will be talking about some new database terminology. One of the most important aspects of modern databases is the fact that they allow you to define relationships. Relationships between tables allow you to break data up into its individual "areas of interest". But when you break the data up, you'll need to know how to put it back together. This is accomplished using relationships, keys and joins. There's plenty to learn about these concepts and we will start by scratching the surface in this episode.
Exciting Announcement As you'll hear in the first few minutes of this episode, I've recently had an epiphone! I realized that there's no great communities dedicated to programmers. So I took it upon myself to create the very first community dedicated to programmers and the pursuit of knowledge and advancement of our common goals (to excel as programmers). You'll learn lots about this community in the episode, so I won't go in to details here, but if you're interested in checking it out - please visit:

What’s all this CRUD about?
This is the at the heart of all databases and SQL. A database essentially carries out these four operations over and over again for the duration of its existence. In this podcast, I talk about these four database operations in detail and the actual syntax that is used in a flavour of SQL known as MySQL. |
Wed, 13 November 2013
Ladies and gentlemen the time has come for you to start learning about Databases and SQL. In this episode I will talk about the very basics of databases and why it is they exist in the first place. You'll learn things like:
Learning and understanding databases is more is less a required skill in these modern days of programming, and at the very least, having knowledge about databases will give you a leg up on any competition. So pay attention boys and girls, and strap on your thinking caps, because this ride is getting started. |

AJAX (Asynchronous Javascript and XML) is a techonology used to create Rich Internet Applications (RIA). If you're asking "what the heck does that mean!?" You're in the right place In this podcast episode we will talk about the uses for AJAX and how it can lead to a much nicer web browsing experience for your Java web applications. What else will you learn about in this episode?

An algorithm is essentially a well defined set of instructions that get carried out by a computer in an automated fashion to solve a problem. A good example of this is to say "How would you tell a computer to figure out which of the 5 balls I've given to you is the heaviest (or lightest)". In order to solve this "problem", you'll need to define a set of steps for the computer to carry out in order to reach a conclusion and solve the problem. Algorithms are very common in programming, as you are constantly trying to tell the computer how to solve problems in a step by step manner. The Big-O Notation is the way we determine how fast any given algorithm is when put through its paces. Consider this scenario: You are typing a search term into Google like "How to Program with Java" or "Java Video Tutorials", you hit search, and you need to wait about 30 seconds before all of the results are on the screen and ready to go... Would you still use Google? Or would you start shopping around with other search engines to find one that is faster? My guess is you'd start shopping around. Speed is everything these days, and building slow software is infuriating to users even if they aren't even paying for the software. |

Ever wondered how you could properly restrict access to certain parts of your web application? Do you have an application that has a user registration page and a user login page? Spring Security is the answer if you have a web application created with the Spring Framework! Spring Security will restrict access to any URLs that point to your web application based on your custom configuration. Learn how in this week's How to Program with Java podcast. |
Wed, 16 October 2013
So, the Spring framework is a wonderful help for programmers, but sometimes it needs a bit of help. It does a good job of trying to match fields on a webpage to Java objects (aka Java Beans), but sometimes when the "mapping" is complex, Spring needs our help. In this episode I will explain exactly how you can go about something known as "custom binding". This process allows you to take any text from the presentation layer and convert/bind it to the appropriate Java object (Java Bean) on the server side. |
Wed, 9 October 2013
In our last episode I talked about controllers and how they are used in Spring. In this episode I will be diving even further into Controllers in the Spring Framework and I will talk about the different parameters that can be passed into each method within each Controller. For example, there are HttpServletRequest objects, Model objects as well as @RequestParam and @ModelAttribute annotations that can be used within your Controller's methods. The beauty of the Spring framework is that you can pick and choose which ones you want to include within any given method. |
Wed, 14 August 2013
Well, so far we've been focusing on a bunch of topics that align themselves around the Java programming language in general. But now we're going to take things into a slightly new direction, we're going to be talking about the Spring Framework -- more specifically, Controllers and the Spring Framework. You see, my goal for this blog and podcast has been to not only teach you the Java programming language, but also teach you how you can build a web application. So, this is the first step in that direction. |

Today let's talk about some design patterns, namely the Observer design pattern which can be used in Java. Following the Oberser design pattern in Java is as easy as extending the Observable object and implementing the Observer interface for the appropriate objects. Don't have a clue what the appropriate objects are? Well then that's what this episode is all about! You'll learn what the design pattern is, how it can be used, and how BIG companies have used it in their powerful frameworks. Don't miss it! |

If you've worked as a developer for a corporation, you've likely been exposed to the waterfall model of software development... If not, consider yourself lucky. I've worked in this model before and it had its issues, but thankfully I was introduced to the Agile development methodology in the latter years of my career as an employee and I got a lot from the experience. This podcast episode is dedicated to talking about the Agile methodology and recounts my experiences with it and how I went through my days using the Agile process. In the episode we will talk about:
Plenty to learn about, and plenty to get excited about! |

Alan Robbins is a self-taught programmer who dabbled with programming in college. After not doing to well in the post-secondary system with respect to programming, he changed his major and graduated with a degree in Business Economics and a minor in Psychology and Philosophy. After graduating, he decided that he had a knack for programming (even if the "system" told him otherwise) so he ended up getting an entry level job as a programmer. Since then, he's started up a couple of businesses and is now running a very successful software development company with 40 employees and "lives the dream" by working from home. |

Knowing how to program with Java is only some of the battle when it comes to developing software, the other major part of the battle is knowing HOW to distribute the software. There are entire schools of thought that surround the ways that you can release software, but in this podcast episode we will focus on two methodologies. The software development life-cycle is the broad term that defines methodologies like:
