How to Change Background Color of a Jbutton on Mouse Hover

In this tutorial, we are going to see how to change the background color of a Jbutton on mouse hover. We can implement MouseListener interface to manage mouse events. The MouseEvent is triggered when we can press, release or click a mouse button on the source object or position the mouse pointer at the input and or output of the source object. We can detect a mouse event when the mouse moves over a component such as a button using mouseEntered() and mouseExited() method of MouseAdapter class or MouseListener interface.
