this code, please explain how impliment 1 mouse checker thing. thanks!

implement mouselistener interface , put code inside mouseclicked(mouseevent e) method. add instance of class listener component.

basically, create class this:

class mymouselistener implements mouselistener {  @override public void mouseclicked(mouseevent arg0) {      //put code want here     //...     //... }  @override public void mouseentered(mouseevent arg0) { }  @override public void mouseexited(mouseevent arg0) { }  @override public void mousepressed(mouseevent arg0) { }  @override public void mousereleased(mouseevent arg0) {  }  } 

then simple create new instance of new class mymouselistener

mymouselistener mml = new mymouselistener(); 

and add listener component. like:

mypanel.addmouselistener(mml);
