Hallo, ich versuche schon seit paar Tagen bei meinem Raster von Button ein Punkt erscheinen zu lassen, also das wenn man einen drückt ein Punkt auf ihm erscheint, ich selber bin neu in Java Gui und kenne mich da kaum bis gar nicht aus. Würde mcih freuen wenn mir jemand helfen könnte
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
