    Default Frustrated lol.

    heres my program :

    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
     
    public class AddSub extends JApplet
    {
    	 int Height = 35;
    	 int Width = 300;
    	private JButton Add;
    	private JButton Sub;
    	private  int num;
    	private JLabel label;
     
    	public void init()
    	{
    		num = 50;
     
    		Add = new JButton("add");
    		Sub = new JButton("subtract");
     
    		Add.addActionListener(new AddButtonListener());
    		Sub.addActionListener(new SubButtonListener());
     
     
    		label = new JLabel("Pushes: "+ Intiger.toString(num));
     
    		Container cp = getContentPane();
    		cp.setBackground(Color.blue);
    		cp.setLayout(new FlowLayout());
     
    		cp.add(add);
    		cp.add(sub);
    		cp.add(label);
     
    		setSize(width,height);
    	}
     
     
    private class AddButtonListener implements ActionListener
    {
    	public void actionPerformed (ActionEvent event)
    	{
    		num++;
    		label.setText("Pushes:" + Intiger.toString(num));
    		repaint();
    	}
    }	
     
     
    private class SubButtonListener implements ActionListener
    {
    	public void actionPerformed (ActionEvent event)
    	{
    		num--;
    		label.setText("Pushes:" + Intiger.toString(num));
    		repaint();
    	}
    }

    Default Re: Frustrated lol.

    It all makes sense. You just made a bunch of spelling and case errors:

    AddSub.java:25: cannot find symbol
    symbol : variable Intiger
    location: class AddSub
    label = new JLabel("Pushes: "+ Intiger.toString(num));
    ^
    It says specifically that it cannot find the symbol: Intiger. Neither can I. I assume you mean Integer.

    AddSub.java:31: cannot find symbol
    symbol : variable add
    location: class AddSub
    cp.add(add);
    ^
    It says it cannot find add. I bet it could find Add.

    AddSub.java:32: cannot find symbol
    symbol : variable sub
    location: class AddSub
    cp.add(sub);
    ^
    Can't find sub; can find Sub.

    AddSub.java:35: width is not public in java.awt.Component; cannot be accessed from outside package
    setSize(width,height);
    ^

    AddSub.java:35: height is not public in java.awt.Component; cannot be accessed from outside package
    setSize(width,height);
    ^
    Another case issue. Your height and width variables are called Height and Width. Since your class extends JApplet and the compiler couldn't find your variables since you used the wrong names, it assumed you were trying to access JApplet's variables named height and width, both of which are not public so you cannot access them directly.

    AddSub.java:44: cannot find symbol
    symbol : variable Intiger
    location: class AddSub.AddButtonListener
    label.setText("Pushes:" + Intiger.toString(num));
    ^
    AddSub.java:55: cannot find symbol
    symbol : variable Intiger
    location: class AddSub.SubButtonListener
    label.setText("Pushes:" + Intiger.toString(num));
    Integer, not Intiger.


    Spelling and Case -- its a bitch.
