Hi,everybody
I want to draw a point wherever in my panel, and I want to make the point visible and I can handle mouse events on it. How can I achieve this? By using Java 2D API? What classes in this API can I use?
Thanks!

Have a nice day

You can use any class you want. However, you may find it most useful to extend JPanel and override it's paint method with one that draws your point via java.awt.Graphics.drawRect with a height and width of one.
Then you can make your JPanel a MouseListener and when you get a mouse click, compare the coordinates of the click with the coordinates of your point.
The Java Tutorial: Creating a GUI covers these concepts and much more.
