Question

This program compiles and works fine. What I need it to do, is instead of coming up with a JOPTION PANE and displaying the information it does, is that I need it to put everything, including what was ordered (i.e the toppings and the size of pizza), into a JTEXT AREA. I am having a crappy time figuring out the JText Area, along with trying to figure out how to get what I need into it. I will rate a lifesaver. Thanks.

The following is the program I have thus far:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import java.text.*;
import javax.swing.*;

public class PizzaOrder extends JFrame implements ActionListener, KeyListener

double meattop1 = 1.50,meattop2 = 1.50,meattop3 = 1.50,meattop4 = 1.50,meattop5 = 1.50,meattop6 = 1.50,meattop7 = 1.50,meattop8 = 1.50,meattop9 = 1.50;

Explanation / Answer

Think of a JTextArea as an extended text field. A text field can hold one line of text, and a JTextArea can hold multiple lines.

To instantiate:

JTextArea txtarea = new JTextArea(5, 40); // this is a JTextArea displaying 5 lines and 40 characters per line

Add it to your instance variables, and instantiate it in your constructor. Then add it to your frame like your JTextFields, but wrap it in a JScrollPane.

add(new JScrollPane(txtarea));

Instead of making a JOptionPane, change the text of the JTextArea.

txtarea.setText("Order confirmed "+text1.getText()+", Thank you" +
" Your pizza will be delivered in a few minutes. ");
