hi I'm creating a program that draw a oval,line,and a rect. but I'm having this problem please can somebody help me
mouseDraw is not abstract and does not override abstract method mouseClicked(java.awt.event.MouseEvent) in java.awt.event.MouseListener
public class mouseDraw extends JApplet implements MouseListener, MouseMotionListener, ActionListener
^
mouseDraw.java:85: missing method body, or declare abstract
public void mouseReleased(MouseEvent e);
^
mouseDraw.java:89: missing method body, or declare abstract
public void mousePressed(MouseEvent e);

please here is my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class mouseDraw extends JApplet implements MouseListener, MouseMotionListener, ActionListener
{
private int mouseX, mouseY, mouseY1, mouseX1;
private JButton[] buttons = new JButton[3];
private JPanel controlPanel, drawPanel;
private int shape;
public void init()
{
buttons[0] = new JButton("Line");
buttons[1] = new JButton("Rectangle");
buttons[2] = new JButton("Oval");
buttons[0].setBackground(Color.red);
controlPanel = new JPanel();
controlPanel.setLayout(new FlowLayout());
controlPanel.setBackground(Color.orange);
drawPanel = new JPanel();
drawPanel.setBackground(new Color(0xffffcc));
for (int i=0; i<3; i++)
controlPanel.add(buttons[i]);
Container pane = getContentPane();
pane.setLayout(new BorderLayout());
pane.add(controlPanel, BorderLayout.NORTH);
pane.add(drawPanel, BorderLayout.CENTER);
for (int i=0; i<3; i++)
buttons[i].addActionListener(this);
addMouseListener(this);
addMouseMotionListener(this);
}
public void paint(Graphics g)
{
super.paint(g);
int x = Math.min(mouseX1, mouseX);
int y = Math.min(mouseY1, mouseY);
g.setColor(Color.blue);
int w = (int)Math.abs(mouseX1 - mouseX);
int h = (int)Math.abs(mouseY1 - mouseY);
switch (shape)
{
case 0: g.drawLine(mouseX1, mouseY1, mouseX, mouseY);
break;
case 1: g.drawRect(x, y, w, h);
break;
case 2: g.drawOval(x, y, w, h);
break;
}
}
public void mouseMoved(MouseEvent e)
{
mouseX = e.getX();
mouseY = e.getY();
showStatus("Mouse is moved to (" + mouseX + mouseY + ")");
}
public void mouseDragged(MouseEvent e)
{
mouseX = e.getX();
mouseY = e.getY();
showStatus("Mouse is moved to (" + mouseX + mouseY + ")");
repaint();
}
public void mouseEntered(MouseEvent e)
{
}
public void mouseExited(MouseEvent e)
{
}
public void mouseReleased(MouseEvent e);
{
}
public void mousePressed(MouseEvent e);
{
mouseX1 = mouseX;
mouseY1 = mouseY;
}
public void actionPerformed(ActionEvent e)
{
for (int i=0; i<3; i++)
{
buttons[i].setBackground(Color.lightGray);
if (e.getSource() == buttons[i])
{
shape = i;
buttons[i].setBackground(Color.red);
}
}

jose,
Just remove the semi-colons at the end of the lines:
mouseReleased and mousePressed
Then create empty method:
mouseClicked
and your program will compile.
Regards,
Manfred.
 
It is sorta covered in the JavaRanch Style Guide.
