import java.awt.event.*;


public class MyApplet extends Applet implements ActionListener {
     TextField t1 = new TextField();
     TextField t2 = new TextField();
     TextField t3 = new TextField();
     Label l1 = new Label("Student Name");
     Label l2 = new Label("Student ID");
     Label l3 = new Label ("Information");

    public MyApplet(){
    setLayout(new GridLayout(3,2));
    button1 = new Button("Add");
    button2 = new Button("Update");
    button3 = new Button("Delete");
       add(l1);
       add(l2);
       add(l3);
       add (t1);
       add (t2);
       add (t3);
       add(button1);
       add(button2);
       add(button3);
       t2.addActionListener(this);
    button1.addActionListener(this);    
    button2.addActionListener(this);
    button3.addActionListener(this);}
@Override
public void actionPerformed(ActionEvent ae) {
    String s1 = t1.getText();
    String s2 = t2.getText();

            if (ae.getSource() == button1){
                        t3.setText(s1+" "+s2);
                        t1.setText("");
                        t2.setText("");
                    } 
                    if (ae.getSource() == button2){
                        t3.setText(s1+" "+s2);
                        t1.setText("");
                        t2.setText("");
                    }
                    if (ae.getSource() == button3){
                        t3.setText("");
                    } }
    Button button1, button2, button3;
}   

I read somewhere that Applet is outdated, but I need this to pass this semester.

(我在某个地方读到Applet已过时，但我需要这个才能通过本学期。)
