maybe someone here can help me. I keep getting an instantiation error (runtime) in my applet code. I'm trying to get an applet to display an image wherever I click the mouse. here's the code:
//< applet code="AppletApp.class" width=200 height=300>< /applet>
import java.awt.*; //<-- added code
import java.applet.*; //<-- added code
import java.awt.event.*; //<-- added code
abstract class AppletApp extends Applet implements MouseListener{

private Image duke;
private int xPos,yPos;

public void init() {

duke = getImage(getDocumentBase(),"duke.gif");
addMouseListener(this);

}
public void paint(Graphics g) {

setBackground(Color.white);
g.drawImage(duke, xPos, yPos, this);
}
public void mousePressed(MouseEvent e) {
xPos = e.getX();
yPos = e.getY();
repaint();
}

}
thanks to anyone who can help
Dave

please help me. I keep getting an instantiation error in my code. it compiles fine, but doesn't work. I'm trying to place an image wherever I click the mouse in the applet.
here's the code
//<applet code="AppletApp.class" width=200 height=300></applet>
import java.awt.*; //<-- added code
import java.applet.*; //<-- added code
import java.awt.event.*; //<-- added code
abstract class AppletApp extends Applet implements MouseListener{

private Image duke;
private int xPos,yPos;

public void init() {

duke = getImage(getDocumentBase(),"duke.gif");
addMouseListener(this);

}
public void paint(Graphics g) {

setBackground(Color.white);
g.drawImage(duke, xPos, yPos, this);
}
public void mousePressed(MouseEvent e) {
xPos = e.getX();
yPos = e.getY();
repaint();
}

}

THis is what I have so far, and I'm getting an instantiation error.
//<applet code="AppletApp.class" width=200 height=300></applet>
import java.awt.*; //<-- added code
import java.applet.*; //<-- added code
import java.awt.event.*; //<-- added code
abstract class AppletApp extends Applet implements MouseListener{

private Image duke;
private int xPos,yPos;

public void init() {

duke = getImage(getDocumentBase(),"duke.gif");

addMouseListener( this );

}
public void paint(Graphics g) {

setBackground(Color.white);
g.drawImage(duke, xPos, yPos, this);
}

public void mousePressed(MouseEvent e) {
xPos = e.getX();
yPos = e.getY();
repaint();
}

}

hey thanks I'll give it a shot and get back to you.

how do I place an image in an applet like a jpeg or gif, and have the applet place the image where I click the mouse?
thanks guys

hey thanks a lot,
that fixed my problem

I'm having a problem with this code. The counters in the "if" statements are not working. Can anyone help me? I've included both files here.
