JAVA用frame实现图中2个窗口 怎么写啊？

图片看起来很模糊，隐约看到需要一个登录窗口，那就分享一下以前练习的登录窗口demo吧。

先上效果图：

登录界面

源码如下：

AbsoluteLoginFrame.java

public class AbsoluteLoginFrame extends JFrame {

private static final int LOGIN_WIDTH = 600;

private static final int LOGIN_HEIGHT = 400;

private static final long serialVersionUID = -2381351968820980500L;

public AbsoluteLoginFrame(){

  //设置窗口标题

  setTitle("登录界面");

  //设置一个初始面板，填充整个窗口

  JPanel loginPanel = new JPanel();

  //设置背景颜色

  loginPanel.setBackground(new Color(204, 204, 204));//#CCC

  loginPanel.setLayout(null);

  JPanel centerPanel = new JPanel();

  centerPanel.setBackground(Color.WHITE);

  centerPanel.setBounds(114, 70, 360, 224);

  centerPanel.setLayout(null);

  JLabel jLabel = new JLabel("用户名：");

  jLabel.setOpaque(true);

  jLabel.setBackground(Color.YELLOW);

  jLabel.setBounds(60, 60, 54, 20);

  JLabel label = new JLabel("密    码：");

  label.setOpaque(true);

  label.setBackground(Color.CYAN);

  label.setBounds(60, 90, 54, 20);

  JTextField textField = new JTextField(15);

  textField.setBounds(130, 60, 166, 21);

  JPasswordField passwordField = new JPasswordField(15);

  passwordField.setBounds(130, 90, 166, 21);

  JButton jButton = new JButton("登录");

  jButton.setBounds(148, 120, 62, 28);

  centerPanel.add(jLabel);

  centerPanel.add(label);

  centerPanel.add(textField);

  centerPanel.add(jButton);

  centerPanel.add(passwordField);

  loginPanel.add(centerPanel);

  getContentPane().add(loginPanel);//将初始面板添加到窗口中

  setSize(LOGIN_WIDTH, LOGIN_HEIGHT);//设置窗口大小

  setLocation(Screen.getCenterPosition(LOGIN_WIDTH, LOGIN_HEIGHT));//设置窗口位置

  setDefaultCloseOperation(EXIT_ON_CLOSE);//设置窗口默认关闭方式

  setResizable(false);

  setVisible(true);

}

public static void main(String[] args) {

  new AbsoluteLoginFrame();

}

}

Screen.java

public class Screen {

private int width;

private int height;

public Screen(){

  Toolkit toolkit = Toolkit.getDefaultToolkit();

  Dimension screenSize = toolkit.getScreenSize();

  this.width = screenSize.width;

  this.height = screenSize.height;

}

public static Point getCenterPosition(int width, int height){

  Screen screen = new Screen();

  int x = (screen.getWidth() - width) / 2;

  int y = (screen.getHeight() - height) / 2;

  return new Point(x, y);

}

public int getWidth() {

  return width;

}

public void setWidth(int width) {

  this.width = width;

}

public int getHeight() {

  return height;

}

public void setHeight(int height) {

  this.height = height;

}

}

求java窗口程序编程？

package window;

import java.awt.Container;

import java.awt.FlowLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JTextArea;

import javax.swing.JTextField;

public class Window extends JFrame{

public static int num = 0;

public static void main(String[] args) {

new Window();

}

public Window(){

//设置x y坐标

this.setLocation(400, 500);

//设置窗口大小

this.setSize(512, 512);

//设置窗口可见

this.setVisible(true);

//设置窗口关闭后程序停止

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//设置窗口不可移动

this.setResizable(false);

JButton but1 = new JButton("按钮");

final JTextField text1 = new JTextField(10);
