Question

JAVA题，请各位牛人帮帮忙！

创建一个应用程序，图形用户界面，上面有三个单选按钮（学习，工作，娱乐），当单击某个单选钮选项时会打开一个相对应的窗口（如点击学习按钮会出现一个新的窗口，上面标题是点击学习选项，标签是学习）

Answer 1

教材里讲到这一章都有例子，你看着改一下就行了，这是最基础的了，你够懒

Answer 2

要用到 对话框组建，你可以找下 ，有关对话框的帮助文档，

Answer 3

是够简单的,最普通的按钮事件么,查一下出就可以了

Answer 4

你找一下API就知道了

Answer 5

文件一，文件名Application2.java，这个文件不用管用JBuilder建工程时候工具会帮你建立。
package db;

import java.awt.Toolkit;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import java.awt.Dimension;

public class Application2 {
boolean packFrame = false;

/**
* Construct and show the application.
*/
public Application2() {
Frame3 frame = new Frame3();
// Validate frames that have preset sizes
// Pack frames that have useful preferred size info, e.g. from their layout
if (packFrame) {
frame.pack();
} else {
frame.validate();
}

// Center the window
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height) {
frameSize.height = screenSize.height;
}
if (frameSize.width > screenSize.width) {
frameSize.width = screenSize.width;
}
frame.setLocation((screenSize.width - frameSize.width) / 2,
(screenSize.height - frameSize.height) / 2);
frame.setVisible(true);
}

/**
* Application entry point.
*
* @param args String[]
*/
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
UIManager.setLookAndFeel(UIManager.
getSystemLookAndFeelClassName());
} catch (Exception exception) {
exception.printStackTrace();
}

new Application2();
}
});
}
}

文件二 文件名Frame3.java
package db;

import java.awt.*;

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

public class Frame3 extends JFrame {
JPanel contentPane;
JRadioButton jRadioButton1 = new JRadioButton();
public Frame3() {
try {
setDefaultCloseOperation(EXIT_ON_CLOSE);
jbInit();
} catch (Exception exception) {
exception.printStackTrace();
}
}

/**
* Component initialization.
*
* @throws java.lang.Exception
*/
private void jbInit() throws Exception {
contentPane = (JPanel) getContentPane();
contentPane.setLayout(null);
setSize(new Dimension(400, 300));
setTitle("Frame Title");
jRadioButton1.setText("学习标签");
jRadioButton1.setBounds(new Rectangle(74, 47, 251, 30));
jRadioButton1.addActionListener(new Frame3_jRadioButton1_actionAdapter(this));
contentPane.add(jRadioButton1);
}

public void jRadioButton1_actionPerformed(ActionEvent e) {
if(jRadioButton1.isSelected()){//判断单选按钮是否被选中,选中为真,未选中为假
Frame4 J=new Frame4();
J.setTitle("学习标签");//设置标题
J.setSize(new Dimension(400,300));//设置大小
J.show();//填出窗体.
}
}
}
class Frame3_jRadioButton1_actionAdapter implements ActionListener {
private Frame3 adaptee;
Frame3_jRadioButton1_actionAdapter(Frame3 adaptee) {
this.adaptee = adaptee;
}

public void actionPerformed(ActionEvent e) {
adaptee.jRadioButton1_actionPerformed(e);
}
}

文件3文件名Frame4.java
package db;

import java.awt.*;

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

public class Frame4 extends JFrame {
JButton jButton1 = new JButton();

public Frame4() {
try {
jbInit();
} catch (Exception exception) {
exception.printStackTrace();
}
}

private void jbInit() throws Exception {
getContentPane().setLayout(null);
jButton1.setBounds(new Rectangle(10, 143, 338, 52));
jButton1.setText("欢迎光临,点击按钮退出");
jButton1.addActionListener(new Frame4_jButton1_actionAdapter(this));
this.getContentPane().add(jButton1, null);
}

public void jButton1_actionPerformed(ActionEvent e) {
System.exit(1);
}
}

class Frame4_jButton1_actionAdapter implements ActionListener {
private Frame4 adaptee;
Frame4_jButton1_actionAdapter(Frame4 adaptee) {
this.adaptee = adaptee;
}

public void actionPerformed(ActionEvent e) {
adaptee.jButton1_actionPerformed(e);
}
}
把这三个文件放在同一个文件夹下从后往前编译，执行Application2就可以了。
