mouse event handling in java using applet

What is a mouse event in Java?
Without a doubt, the most commonly used mouse event in Java programs (and any other program written for a graphical user interface) is the event, which is generated whenever the user clicks within an applet. It's the event, for example, that lets Java know when an on-screen button component has been clicked.
How does the applet respond to mouse clicks?
The applet in Listing 25.1 responds to mouse clicks by printing the word "Click!" wherever the user clicks in the applet. It does this by storing the coordinates of the mouse click in the applet's coordY data fields. The paint () method then uses these coordinates to display the word. Figure 25.1 shows MouseApplet running under Appletviewer.
How do I handle a mouse event?
Working with the Mouse The basic event-handling idea should be familiar by now: register as a listener, handle the event when it occurs, using information obtained from the corresponding Eventobject There are some differences to note however:
How to use ActionListener & mouselistener in Java?
Here, we will use the ActionListener on Button and MouseListener when the event has occurred through mouse activities. We need to import the essential packages like Applet and AWT for customization. When the packages get imported, then we need to create the class that implemented the ActionListener and MouseListener interface in Java.
