    Default GridLayout/JButton/MouseListener question

    Hey everyone. I'm trying to create a MouseListener event so that when a Tile is clicked on my grid it will black out all tiles that are of the same color as the one I clicked, except the one I clicked.

    A little background on what my code does so far: When I run the program it creates a GameBoard of JButton's and then colors them in using my colorTiles() method. After that it's supposed to shuffle them up and distribute them randomly across the board but I haven't gotten that far yet.

    here is my code so far

    import java.awt.BorderLayout;
    import java.awt.Color;
    import java.awt.Container;
    import java.awt.Dimension;
    import java.awt.FlowLayout;
    import java.awt.GridLayout;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.awt.event.MouseEvent;
    import java.awt.event.MouseListener;
    import java.util.Arrays;
    import java.util.Collections;
    import java.util.Random;
     
    import javax.swing.JButton;
    import javax.swing.JFileChooser;
    import javax.swing.JFrame;
    import javax.swing.JMenu;
    import javax.swing.JMenuBar;
    import javax.swing.JMenuItem;
    import javax.swing.JPanel;
     
    @SuppressWarnings("serial")
    public class GameBoard extends JFrame{
    	private int numRows = 16, numCols = 16;
    	Tile[][] myTiles;
    	Tile[] t = new Tile[256];
    	JButton board;
    	private MyEventHandler eh = new MyEventHandler();
     
    	public static void main(String[] args) {
    		new GameBoard();
    	}
     
    	public GameBoard() {
    		setSize(800,800);
     
    		Container c = getContentPane();
    		c.setLayout(new BorderLayout());
     
    		setDefaultCloseOperation(EXIT_ON_CLOSE);
    		setTitle("Random Colors");
     
    		JButton tilePanel = buildTiles();
    		c.add(tilePanel, BorderLayout.CENTER);
     
    		setResizable(false);
    		setVisible(true);
    	}
     
    	private JButton buildTiles() {
    		board = new JButton();
    		board.setBackground(Color.BLACK);
    		board.setPreferredSize(new Dimension(800, 800));
    		board.setLayout(new GridLayout(numRows, numCols));
    		colorTiles();
     
    		return board;
    	}
     
    	public void colorTiles() {
    		for(int i = 0; i < t.length; i++){
    			if(i < 39){
    				t[i] = new Tile(Color.YELLOW);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    			else if(i >= 39 && i < 85){
    				t[i] = new Tile(Color.RED);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    			else if(i >= 57 && i < 119){
    				t[i] = new Tile(Color.BLUE);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    			else if(i >= 119 && i < 171){
    				t[i] = new Tile(Color.GREEN);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    			else if(i >=171 && i < 212){
    				t[i] = new Tile(Color.MAGENTA);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    			else if(i >= 212 && i < 256){
    				t[i] = new Tile(Color.CYAN);
    				t[i].setColor();
    				board.add(t[i]);
    			}
    		}
    	}
     
    	public void shuffle() {
    		Collections.shuffle(Arrays.asList(t));
    	}
     
     
    	private class MyEventHandler implements MouseListener {
     
    		@Override
    		public void mouseClicked(MouseEvent e) {
    		}
     
    		@Override
    		public void mouseEntered(MouseEvent arg0) {
    			// TODO Auto-generated method stub
     
    		}
     
    		@Override
    		public void mouseExited(MouseEvent arg0) {
    			// TODO Auto-generated method stub
     
    		}
     
    		@Override
    		public void mousePressed(MouseEvent arg0) {
    			// TODO Auto-generated method stub
     
    		}
     
    		@Override
    		public void mouseReleased(MouseEvent arg0) {
    			// TODO Auto-generated method stub
     
    		}
     
    	}
     
    }

    import java.awt.Color;
    import java.util.Arrays;
    import java.util.Collections;
    import java.util.Random;
    import javax.swing.JButton;
     
    @SuppressWarnings("serial")
    public class Tile extends JButton{
    	Color color;
    	Tile[] colors = new Tile[256];
    	Tile[][] myTiles;
     
    	public Tile(Color c) {
    		color = c;
    	}
     
    	public Tile() {
     
    	}
     
    	public void setColor() {
    		for(int i = 0; i < colors.length; i++){
    			setBackground(color);
    			paintImmediately(0, 0, getWidth(), getHeight());
    		}
    	}
    }

    I guess my question is, how would I go about doing this and where do I start? do I need to make a new method or can I write some code in the mouseClicked method and how do I give my tiles the ability to detect a mouse click?

    how do I give my tiles the ability to detect a mouse click
    You can add an action listener to the Tile class objects because it extends the JButton class.
