Teaching novice computer programmers how to turn their ideas into working applications
In the last post we saw how you can easily create a JTree using an array of strings. The JTree however did not display the values in a hierarchy but displayed all the values at the same level. So in this post we will build our Java Desktop Application using JTree with a hierarchy.
JTree is a Swing class used display a tree like structure such as the one shown below.
I am a firm believer in code comments among other things. So when I came across a blog post at http://blog.jooq.org/2013/12/04/when-source-code-comments-indicate-trouble/ talking about amusing comments coders leave in their code for people to find later I followed the links and found this: Continue reading “Code Comments”
In this tutorial we will take a look at displaying JTree information in a hierarchy. We will introduce the Tree Node object that works alongside JTree. As we go through the tutorial we will see how the Tree Node handles the tree data and the JTree takes care of displaying the information. Continue reading “Using JTree to display a hierarchy”
In this tutorial we walk through the files in a file system. As we go through the directories and sub directories we identify specific file types using file filters. In this example image files of various formats are selected. Continue reading “Select files using file filters”
Lots of people set out to learn a language, take a course and then at the end of it don’t know what to do next. They don’t feel they are a coder, they still can’t do anything of substance. We all go through this. There is a chasm between knowing a programming language and being able to do things with it. The next step is to learn to write an application. Continue reading “Having learnt the language now what?”
If you ask this question, there will be an avalanche of responses. The responses will probably be of the type, learn this language because its new/it’s in demand/it pays well.

I see lots of posts around the web about people who are interested in learning to program. From the questions they ask you can tell they have aspirations to be the next best thing since sliced bread. While all of this unharnessed enthusiasm is great we all need a sense of reality. So, what does it take to be a programmer?

People often post questions on the internet about how to become a top class
programmer. When I look at these posts I think about how I got from knowing nothing to being confident about coding. Continue reading “So you want to be a programmer? – love programming”
In an earlier post I listed Five ways to faster learning. Now all these ideas centred around having a plan on how you are going to learn. You need to decide where you are going and how you are going to get there. All make sense? Continue reading “You Don’t Know What You Don’t Know”
