下面的程序與上一例有一點差別，細致對照不難發現當中的不同之處。

package com.beyole.util;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;

public class test17 {
	public static void main(String[] args) {
		JFrame frame = new JFrame("Crystal");
		JTextField nameField = new JTextField(30);
		JTextField location = new JTextField("beyole", 10);
		JLabel name = new JLabel("輸入姓名");
		JLabel locat = new JLabel("所屬單位");
		location.setEnabled(false);
		name.setBounds(10, 10, 100, 20);
		locat.setBounds(10, 40, 100, 20);
		nameField.setBounds(80, 10, 90, 20);
