If you need to create a Thread in Java, and cannot extend the Thread class, often because you are extending another class, you can always implement Runnable. Notice, that just like where you extend the Thread class, you have to override the abstract method run. However, in this example, you need to create a Thread…
One of the two ways to use a thread in Java is to extend the Thread object. It can be done like the following. Of course this is only good if you are not extending another Class. You must override the run method, and you will need to call start() to start the thread and…
Now that we’ve looked at some basic Layout Manager options, lets dive into building one.

Why we use Combo Boxes Combo boxes are a drop down menu option for forms. They allow us to limit the number of potential choices for a person to make, increasing the chance of a person picking a valid and correct option. In our example where we were extending a class for a Java GUI,…
