Applet to change text color

Hello guys, I'm sort of a beginner to java and they gave us this program in school which I can't seem to compile. It's basically an applet to change color of text as the user wishes. Here's the code:

Code:

---

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class AnimateColor extends Applet implements ActionListener
{
Button b;
Label l;
TextField tf;
String msg="Font animation";
public Animatecolor()
{
super();
}
public void destroy()
{
}
public void init()
{
l=new Label("Enter color");
tf=new TextField(15);
b=new Button("CHANGE");
add(l);
add(tf);
add(b);
setLayout(null);
l.setBounds(40,40,150,20);
tf.setBounds(200,40,200,40);
b.setBounds(100,80,100,40);
b.addActionListener(this);
}
public void start()
{
}
public void paint(Graphics g)
{
g.drawString(msg,100,100);
}
public void stop()
{
}
public void actionperformed(ActionEvent ae)
{
String st=ae.getActionCommand();
String s=tf.getText();
if(s.equalsIgnoreCase("red"))
setForeground(Color.red);
else
if(s.equalsIgnoreCase("yellow"))
setForeground(Color.yellow);
else
if(s.equalsIgnoreCase("blue"))
setForeground(Color.blue);
else
if(s.equalsIgnoreCase("black"))
setForeground(Color.black);
else
if(s.equalsIgnoreCase("cyan"))
setForeground(Color.cyan);
tf.setText("");
}
}

The error I am getting at compilation is
"AnimateColor.java:10: Invalid method declaration; return type required"
Any help would be appreciated!!

Java is case sensitive, check the definition of the constructor defined in your code...if its not the same (both in spelling and case) as the class the compiler thinks its a method declaration (which requires a return type)

Great spot there I must say! Didn't realize that little mistake till you pointed it out. But even after I've made the change there's still an error. But this time it says:

Quote:

AnimateColor.java:4: AnimateColor is not abstract and does not override abstract method actionPerformed(java.awt.event.ActionEvent) in java.awt.event.ActionListener

---

And if I change the 4th line to:
public abstract class AnimateColor extends Applet implements ActionListener
The code compiles but the applet doesn't run in html!

No, you're correcting the wrong thing. That error message is not telling you to make your class abstract but rather to implement all the methods of any interface that the class implements. Solution: implement the methods, in this case one -- and the error message even tells you which one!

But how do I do that? I'm sorry but I'm a real rookie at this!

Ok I made this change:

public void actionPerformed(ActionEvent ae)

And now the code compiles and runs in html. But the string "Font Animation" isn't appearing!! What could the reason be?

We have no clue about your project and changes you made, so you must provide context...preferably a Short, Self Contained, Correct Example that demonstrates the problem

Got it... turns out I had to just increase the width and height of the applet window in the html file. Program works fine now! Thanks for all the help anyways!
