swing - Java GUI hides windows taskbar

Question

I am using JFrame to create my GUI for a desktop application. The size of the GUI I am setting according to the resolution of the platform screen using this code.

this.setSize(this.getToolkit().getScreenSize());

The problem is that when I run the application the GUI covers all of the screen. The Windows task-bar is also hidden behind the GUI.

I want that whatever the size of the task-bar is, the task-bar should be visible in all conditions. How do I achieve that?

Since you are using a JFrame you should just call:

jFrame.setExtendedState(JFrame.MAXIMIZED_BOTH);

This takes into account the position of the taskbar.
