Chess Application In Java Swing

     

In this section, you will learn how to create chess game in java swing.

In the given example, we have defined MouseListener, MouseMotionListener perform two actions. This chess simulator will help you to master your chess playing skills, to train your intellectual capacity and give you lots of entertainment.  Mouse events notify when the user uses the mouse to interact with a component. Mouse events occur when the cursor enters or exits a component's on screen area and when the user presses or releases one of the mouse buttons.

Here is the Code.
