JTextFields with labels

[Java Junior]

Hello all, Can anyone tell me how I can include a label for my JTextBoxes, so for example inside the first textbox it says "Enter first number" then when I click inside the box the text disapears? Or if that is too long to do then how about a little label obove the textbox saying "first number" then obove the second box saying "second number" or something along those lines :)

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;


public class Calc extends JApplet {
    JTextField int1, int2, out;
    JButton plus;
    public void init(){
        int1 = new JTextField(8);
        int2 = new JTextField(8);
        out = new JTextField(15);
        out.setEditable(false);
        plus = new JButton("+");
        JPanel panel = new JPanel();
        JPanel panel2 = new JPanel();
        add(panel, BorderLayout.CENTER);
        add(panel2, BorderLayout.SOUTH);
        plus.addActionListener(new ButtonHandler(this));
        panel.add(int1);
        panel.add(int2);
        panel.add(out);
        panel2.add(plus);
    }
}

class ButtonHandler implements ActionListener{
    Calc theApplet;
    ButtonHandler(Calc app){
        theApplet = app;
    }

    public void actionPerformed(ActionEvent e) {
        try{
            int integer1 = Integer.parseInt(theApplet.int1.getText());
            int integer2 = Integer.parseInt(theApplet.int2.getText());
            if(e.getSource()==theApplet.plus)
                theApplet.out.setText(String.valueOf(integer1 + integer2));
    }catch(NumberFormatException invalid){
            theApplet.out.setText("Must use numbers");
        }
    }
}
