JAVA GUI Problem

[Doug Cates]

I am trying to complete an assignment that converts all lower case letters to uppercase in a GUI. This is what I have so far:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class A3CA3205890 {
   
   private static class Caps extends JPanel {
      public void paintComponent(Graphics g) {
         super.paintComponent(g);
         g.drawString( String s = "The Gators Rule";
        String s2 = s.toUpperCase();
        System.out.println(s2); 20, 30 );
 
}
}
   private static class ButtonHandler implements ActionListener {
      public void actionPerformed(ActionEvent e) {
         System.exit(0);
      }
   }
   
   public static void main(String[] args) {
 
      
      Caps displayPanel = new Caps();
      JButton okButton = new JButton("OK");
      ButtonHandler listener = new ButtonHandler();
      okButton.addActionListener(listener);
 
      JPanel content = new JPanel();
      content.setLayout(new BorderLayout());
      content.add(displayPanel, BorderLayout.CENTER);
      content.add(okButton, BorderLayout.SOUTH);
 
      JFrame window = new JFrame("A3CA3205890 JAVA GUI");
      window.setContentPane(content);
      window.setSize(500,200);
      window.setLocation(100,100);
      window.setVisible(true);
 
   }
   
}

I think that I am doing something dumb in the

   private static class Caps extends JPanel {
      public void paintComponent(Graphics g) {
         super.paintComponent(g);
         g.drawString( String s = "The Gators Rule";
        String s2 = s.toUpperCase();
        System.out.println(s2); 20, 30 );
 
}
}

portion.

Any help would be very appreciated.
Thanks

These three lines:

g.drawString( String s = "The Gators Rule";
String s2 = s.toUpperCase();
System.out.println(s2); 20, 30 );


Look like the victim of a bad cut and paste. The first line is only part of a valid statement; the middle line is a complete valid statement, while the last line is a valid statement follows by what looks like the missing part of the first line.

Now, if this much isn't obvious to you, then it sounds like you have some pretty basic larnin' to do. Do you understand methods, method calls, arguments, stuff like that? If not, then that's where we've got to start.

Thanks, you are right. I wrote part of it, got some help and then copied the two together. Been spending too many hours doing this. I figgered it was something simple. Thanks
