JAVA PAINT

[blankspace]

Hello,
I need help with java.
I need to create an application that is similar with paint but slightly different.

Here is the description of this project that i need to work on.

First, we need to display a menu that is consist of two choices which is 'custom animation' and 'custom brush'.

For example, if we click on 'custom brush', a variety of brushes will appear, and we can try to use them on the drawpad.
And if we click on 'custom animation', we can animate the image or shapes that we have chosen. We can bounce the shape or etc.

For now, I have just finished the coding for the menu.

May I ask you your help to assist me to finish the project please? Thank you

ps : i have no idea to create the interface (or whatever it is called hehe) for the custom brushes and the animation one

yes, you can ask help here.
the way it goes is:
you post a specific question
you post the relevant code

package project;

import java.awt.event.*;

import javax.swing.*;

class Menu {

    public static void main(String[] args) {

        Runnable r = new Runnable() {
            public void run() {
                final JButton b = new JButton("PLEASE SELECT CUSTOM DOCUMENT");

                final JPopupMenu menu = new JPopupMenu("Menu");
                menu.add("CUSTOM DOCUMENT BRUSHES");
                menu.add("CUSTOM DOCUMENT SHAPES");
                menu.add("CUSTOM DOCUMENT ANIMATION");
                b.addActionListener( new ActionListener() {
                    public void actionPerformed(ActionEvent ae) {
                        menu.show(b, b.getWidth()/2, b.getHeight()/2);
                    }
                } );
                JOptionPane.showMessageDialog(null,b);
            }
        };
        SwingUtilities.invokeLater(r);
    }
}

So, i have this code as the menu and this code below as the brush code (but not complete yet) which i got from the internet. I have modified the code to help me understand the use of it. And luckily, i do understand the code.

This is the code :

package project;

import javax.swing.SwingUtilities;

import java.awt.Image;
import java.awt.image.BufferedImage;
import javax.swing.filechooser.FileFilter;
import javax.swing.filechooser.FileNameExtensionFilter;
import java.io.*;
import javax.swing.JLabel;

So, my question now is, how do i link the codes so that if i click on the 'custom document brush' on the menu, the brush app will appear? thank you.
