UPDATE:

Sorry about not following concurrency in Swing.

Here is updated answer:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JApplet;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
import javax.swing.SwingUtilities;
import javax.swing.Timer;

public class ClassTestHello extends JApplet {
  private static JPanel j1;
  private JLabel jl;
  private JPanel j2;
  private Timer timer;
  private int i = 0;
  private int[] a = new int[10];

  @Override
  public void init() {
    SwingUtilities.invokeLater(new Runnable() {
      public void run() {
        start();
        paint();
      }
    });
  }

  public void paint() {
    jl = new JLabel("hiii");
    j1.add(jl);

    a[0] = 1000;
    a[1] = 800;
    a[2] = 900;
    a[3] = 2000;
    a[4] = 500;

    ActionListener actionListener = new ActionListener() {
      public void actionPerformed(ActionEvent actionEvent) {
        if(i % 2 == 0)
          jl.setText("hiii");
        else
          jl.setText("byee");

        i++;
        if(i > 4)
          i=0;
        timer.setDelay(a[i]);
      }
    };

    timer = new Timer(a[i], actionListener);
    timer.setInitialDelay(0);
    timer.start();
  }

  @Override
  public void start() {
    j1 = new JPanel();
    j2 = new JPanel();

    JTabbedPane jt1 = new JTabbedPane();

    ImageIcon ic = new ImageIcon("e:/guitar.gif");
    JLabel jLabel3 = new JLabel(ic);
    j2.add(jLabel3);

    jt1.add("one", j1);
    jt1.addTab("hii", j2);

    getContentPane().add(jt1);    
  } 
}
