求代碼:利用Java做一個新的彈出窗口的小程序

重點(diǎn)地是窗體彈出類：WindowsCenter.java

文件一父窗文件名Frame3.java

package untitled1;

import java.awt.BorderLayout;

import javax.swing.JFrame;

import javax.swing.JButton;

import java.awt.*;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

public class Frame3 extends JFrame {

JButton jButton1 = new JButton();

public Frame3() {

try {

jbInit();

} catch (Exception exception) {

exception.printStackTrace();

}

}

private void jbInit() throws Exception {

getContentPane().setLayout(null);

setSize(400,400);

jButton1.setBounds(new Rectangle(86, 125, 186, 52));

jButton1.setText("點(diǎn)擊彈出一個窗口");

jButton1.addActionListener(new Frame3_jButton1_actionAdapter(this));

this.getContentPane().add(jButton1, null);

}

public void jButton1_actionPerformed(ActionEvent e) {

this.dispose();//釋放當(dāng)前窗口

WindowsCenter.Center(new Frame2());//彈出第三個窗口

}

public static void main (String[] args)

{

WindowsCenter.Center(new Frame3());//彈出主窗口

}

}

class Frame3_jButton1_actionAdapter implements ActionListener {

private Frame3 adaptee;

Frame3_jButton1_actionAdapter(Frame3 adaptee) {

this.adaptee = adaptee;

}

public void actionPerformed(ActionEvent e) {

adaptee.jButton1_actionPerformed(e);

}

}

//要彈出的子窗口文件名：Frame2.java

package untitled1;

import java.awt.*;

import javax.swing.*;

import java.awt.Rectangle;

import java.awt.event.ActionListener;

import java.awt.event.ActionEvent;

public class Frame2 extends JFrame

{

private JButton jButton1=new JButton();

public Frame2 ()

{

try {

jbInit();

}

catch(Exception exception) {

exception.printStackTrace();

}

this.setVisible(true);

}

private void jbInit () throws Exception

{

this.setBounds(300,180,400,300);

getContentPane().setLayout(null);

jButton1.setBounds(new Rectangle(127, 120, 139, 36));

jButton1.setMnemonic('C');

jButton1.setText("點(diǎn)我(C)");

jButton1.addActionListener(new ActionListener()

{

public void actionPerformed (ActionEvent e)

{

jButton1_actionPerformed(e);

}

});

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

this.getContentPane().add(jButton1);

}

public void jButton1_actionPerformed (ActionEvent e)

{

this.setVisible(false);

JFrame jf1=new JFrame("子窗口");

jf1.setBounds(100,50,800,600);

jf1.setDefaultCloseOperation(jf1.EXIT_ON_CLOSE);

jf1.setVisible(true);

}

}

//窗體居中彈出類文件名：WindowsCenter.java類

package untitled1;

import java.awt.Toolkit;

import java.awt.Dimension;

import javax.swing.*;

//窗體居中類

public class WindowsCenter {

public WindowsCenter() {

}

public static void Center(JFrame frame){

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.show();

}

}

//將這三個文件分別編譯后執(zhí)行

第二個文件名是Frame1.java，用命令javac Frame1.java可以編譯，命令java Frame1.class可以執(zhí)行

Java編寫一個簡單的窗口程序

package inter.frame;import java.awt.BorderLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;public class MenuTest { /**

* @param args

*/

JFrame frame;

JMenuBar mb;

JMenu m;

JMenuItem mi1;

JMenuItem mi2; public MenuTest() {

initFrame();

initAction();

} public void initFrame() {

frame = new JFrame();

mb = new JMenuBar();

m = new JMenu("學(xué)生查詢");

mi1 = new JMenuItem("確認(rèn)");

mi2 = new JMenuItem("取消"); m.add(mi1);

m.add(mi2);

mb.add(m);

frame.add(mb, BorderLayout.NORTH);

frame.setSize(300, 300);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

} public void initAction() {

mi1.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

System.out.println("click");

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了確定按鈕");

}

});

mi2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了取消按鈕");

}

});

} public static void main(String[] args) {

// TODO Auto-generated method stub

new MenuTest();

}}

用java做一個窗口

java做窗口的話，需要用swing技術(shù)，之后創(chuàng)建JFrame 等組件，即可完成窗口創(chuàng)建工作。

package inter.frame;import java.awt.BorderLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;public class MenuTest { /**

* @param args

*/

JFrame frame; //定義一個窗口架構(gòu)

JMenuBar mb;//定義窗口的菜單工具欄

JMenu m; //定義菜單

JMenuItem mi1;//定義菜單的內(nèi)容

JMenuItem mi2; //定義菜單的內(nèi)容

public MenuTest() {

initFrame();

initAction();

}

public void initFrame() {

frame = new JFrame();

mb = new JMenuBar();

m = new JMenu("學(xué)生查詢");

mi1 = new JMenuItem("確認(rèn)");

mi2 = new JMenuItem("取消"); m.add(mi1);

m.add(mi2);

mb.add(m);

frame.add(mb, BorderLayout.NORTH);

frame.setSize(300, 300); //設(shè)置窗口大小

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//設(shè)置退出時關(guān)閉窗口

frame.setVisible(true);//設(shè)置窗口可見

} public void initAction() {

mi1.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

// 具體實現(xiàn)代碼根據(jù)實際要求填寫

System.out.println("click");

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了確定按鈕");

}

});

mi2.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

// 具體實現(xiàn)代碼根據(jù)實際要求填寫

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了取消按鈕");

}

});

} public static void main(String[] args) {

new MenuTest();//執(zhí)行菜單創(chuàng)建

}}

java程序關(guān)閉窗口代碼

import?java.applet.*;

import?java.awt.Color;

import?java.awt.Frame;

import?javax.swing.JFrame;

import?java.awt.event.*;

public?class?FirstFrame?extends?Frame?{

public?static?void?main(String?args[])?{

FirstFrame?fr?=?new?FirstFrame("First?contianer!");

fr.setSize(240,?240);

//繼承JFrame的關(guān)閉窗口代碼

//fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//繼承Frame的

fr.addWindowListener(new?WindowAdapter()?{????

public?void?windowClosing(WindowEvent?e)?{????????

System.exit(0);//退出系統(tǒng)???

}

});

fr.setVisible(true);

}

public?FirstFrame(String?str)?{

super(str);

}

}
