problems with ClickMe Applet
I'm very new to Java and need help with a basic inquiry.
I have typed the following two sets of code from the java tuturial to run an applet where the user clicks and sees a red dot appear on the screen/
the code for ClickMe does not compile. The two errors I rcvd in terms of syntax do not make sense because I have verified again and again and the code is exactly as given in the tutorial. So I forcefully compile it using the set classpath= to get the ClickMe class. When I run the html file, I get error saying that it cannot find and load the ClickMe class.
Here are the two sets of code:
First file is called Spot:
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class Spot{
public int size;
public int x, y;
public Spot(int intSize) {
size=intSize;
size=intSize;
x=-1;
y=-1;
}
}
This is the second java file ClickMe, I have used arrows to point to two lines where I get the error, the first is line 2 and the second is line 21.
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class ClickMe extends Applet implements MouseListener{
private Spot spot=null; //<-error one points to this line
private static final int RADIUS=7;
public void init(){
addMouseListener(this);
}
public void paint(Graphics g){
g.setColor(Color.white);
g.fillRect(0,0,getSize().width- 1,getSize().height- 1);
g.setColor(Color.black);
g.drawRect(0,0,getSize().width- 1,getSize().height- 1);
g.setColor(Color.red);
if(spot!=null){
g.fillOval(spot.x - RADIUS,
spot.y - RADIUS,
RADIUS*2, RADIUS*2);
}
}
public void mousePressed(MouseEvent event){
if(spot==null){
spot=new Spot(RADIUS); /*<--Error 2 points to the capital "S" in Spot*/
}
spot.x=event.getX();
spot.y=event.getY();
repaint();
}
public void mouseClicked(MouseEvent event) {}
public void mouseReleased(MouseEvent event) {}
public void mouseEntered(MouseEvent event) {}
public void mouseExited(MouseEvent event) {}
}
Much appreciated if someone could take a look at this.
