    int count=0;
    Panel main = new Panel();

    public lang()
    {
    super("Typing Application");
    label1 = new JLabel("Type some text using your keyboard. The keys you press will be
    "+ "highlighed and the text will be displayed");
    add(label1);

    any action");
    add(label2);
    textField = new JTextField(30);
    textField.setEditable(false);

    for(int i=0; i<13; i++)
    {
    first[i] = new JButton(firstRow[i]);
    first[i].setSize(100,100);
    keys1.add(first[i]);
    first[i].addActionListener(new TextAreaHandler());
    }



    main.add(keys1);
    for(int i=0; i<13; i++)
    {
    second[i] = new JButton(secondRow[i]);
    second[i].setBackground(Color.white);
    keys2.add(second[i]);
    second[i].addActionListener(new TextAreaHandler());
    }

    main.add(keys2);

    for(int i=0; i<12; i++)
    {
    String t=i+"";
    String m="icon";
    String n=".gif";
    String s=m+t+n;
    ImageIcon img = new ImageIcon(s);
    third[i] = new JButton(img);
    keys3.add(third[i]);
    third[i].addActionListener(new TextAreaHandler());
    }

    main.add(keys3);
    int j=12;

    for(int i=0; i<12; i++)
    {
    String t=j+"";
    String m="icon";
    String n=".gif";
    String s=m+t+n;
    ImageIcon img = new ImageIcon(s);
    fourth[i] = new JButton(img);
    keys4.add(fourth[i]);
    j++;
    fourth[i].addActionListener(new TextAreaHandler());
    }

    public class hindilang
    {
       public static void hindi()
          {
             lang lang = new lang()
               {
                 public void keyTyped(KeyEvent e) 
                   {
                        throw new UnsupportedOperationException("Not supported yet.");
                   }
                 public void keyPressed(KeyEvent e) 
                   {
                        throw new UnsupportedOperationException("Not supported yet.");
                   }
                 public void keyReleased(KeyEvent e)
                   {
                        throw new UnsupportedOperationException("Not supported yet.");
                   }
               };
           }
    } 
            lang.setSize(800, 500); // set dimensions of window
            lang.setVisible(true);
    }
    }

The File is saved as hindilang.java and being compiled as javac hindilang.java, What am i doing wrong?? Please guide me
