在本例演示了JTextField,JTextArea,JPasswordField,JCheckBox(复选框按钮),JRadioButton(下拉列表框组件),JLabel等基本组件的用法。

需要注意的是:若多个JRadioButton需要归为一组时,需要把这些JRadioButton使用add()方法添加到ButtonGroup中对象。

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class TestRegister extends JFrame {
    private static final long serialVersionUID = 1L;
    JLabel uname,passwd,confpasswd,sex,utype,like,introduce;
    JPasswordField pf1,pf2;
    JButton submit,reset;
    JTextField tf;
    JTextArea intro;
    JCheckBox reading,writing,chatting;
    JRadioButton m,f;
    JComboBox cb;
    TestRegister(String name)
    {
        super(name);
        this.setVisible(true);
        this.setBounds(400,300,400,400);
        this.setLayout(new GridLayout(8,2));
        this.addWindowListener(new WindowAdapter()
        {
            public void windowClosing(WindowEvent e)
            {
                System.exit(0);
            }
        });
        
    }
    public void init()
    {
        uname = new JLabel("用户名");
        passwd = new JLabel("密码");
        confpasswd = new JLabel("确认密码");
        sex = new JLabel("性别");
        utype = new JLabel("用户类别");
        like = new JLabel("爱好");
        introduce = new JLabel("简介");
        
        pf1 = new JPasswordField(10);
        pf2 = new JPasswordField(10);
        
        submit = new JButton("提交");
        reset = new JButton("重置");
        
        tf = new JTextField(10);
        intro = new JTextArea(3,10);
        
        reading = new JCheckBox("Reading");
        writing  = new JCheckBox("Writing");
        chatting = new JCheckBox("Chatting");
        
        m = new JRadioButton("男");
        f = new JRadioButton("女");    
        
        cb = new JComboBox();
        cb.addItem("管理员");
        cb.addItem("会员");
        cb.addItem("游客");
        
        ButtonGroup bg = new ButtonGroup();
        bg.add(m);
        bg.add(f);
        
        JPanel p1 = new JPanel();
        p1.add(m);
        p1.add(f);
        
        JPanel p2 = new JPanel();
        p2.add(reading);
        p2.add(writing);
        p2.add(chatting);
        
        JPanel p3 = new JPanel();
        JPanel p4 = new JPanel();
        p3.add(submit);
        p4.add(reset);
        
        this.add(uname);
        this.add(tf);
        this.add(passwd);
        this.add(pf1);
        this.add(confpasswd);
        this.add(pf2);
        this.add(sex);
        this.add(p1);
        
        this.add(utype);
        this.add(cb);
        this.add(like);
        this.add(p2);
        
        this.add(introduce);
        this.add(intro);
        this.add(p3);
        this.add(p4);
            
        this.pack();
    }
    public static void main(String[] args) {
        new TestRegister("user Register").init();
    }

}
