java的一个窗体建立

我已发送邮件到你的邮箱，我的邮箱是fengxk2004@163.com

Java源程序附后。

本程序的特点是：

(1) 文本框只能输入纯数字；

(2) 界面较美观；

(3) 代码可读性较好，有适当的注释；

(4) 窗体一出现就在桌面居中。

import java.awt.*;

import javax.swing.*;

public class GuessNumber {

private static final long serialVersionUID = 1L;

JFrame frame;

java怎么做窗体

如果是要进行AWT或者Swing编程需要将类打包成可运行的jar包或者通过工具将jar包打包成exe文件，然后点击就可以直接运行了。下面是一个简单的登录窗口例子：

效果图：

代码：

import java.awt.*;

import java.awt.event.*;

public class TestTextField implements ActionListener{

TextField name;

TextField password;

public static void main( String args[]) {

TestTextField ttf = new TestTextField();

ttf.createUI();

}

public void createUI(){

Frame f = new Frame("登录界面");

f.add(new Label("请输入您的用户信息:"),"North");

Panel p1 = new Panel();

p1.setLayout(new BorderLayout());

Panel p11 = new Panel();

p11.setLayout(new GridLayout(2,1));

p11.add(new Label("用户名:"));

p11.add(new Label("密码:"));

Panel p12 = new Panel();

p12.setLayout(new GridLayout(2,1));

name = new TextField(10);

name.addActionListener(this);

password = new TextField(10);

password.setEchoChar('*');

password.addActionListener(this);

p12.add(name);

p12.add(password);

p1.add(p11,"West");

p1.add(p12,"Center");

Panel p2 = new Panel();

Button submit = new Button("提交");

Button reset = new Button("重置");

submit.addActionListener(this);

reset.addActionListener(this);

p2.add(submit);

p2.add(reset);

f.add(p1,"Center");

f.add(p2,"South");

f.addWindowListener(new WindowAdapter(){

public void windowClosing(WindowEvent e){

System.exit(0);

}

});

f.setSize(200,130);

f.setLocation(300,200);

f.setVisible( true);

}

public void actionPerformed(ActionEvent e){

String s = e.getActionCommand();

if(s.equals("重置")){

this.clear();

}else if(s.equals("提交") || (e.getSource()==name) || (e.getSource()==password)){

this.submit();

}

public void clear(){

name.setText("");

password.setText("");

}

public void submit(){

String n = name.getText();

String psw = password.getText();

System.out.println("用户名:" + n + "\t密码:" + psw);

}

更多关于窗口的编写请查看：

刚学java想做个小游戏，请教各位高手大侠，如何限制图片在窗体中的移动范围，只能限制坐标吗？好像很麻烦呀

你是在说游戏背景图片吗？有的时候会出界？

如果是的话可以创建两个矩形，一个是背景图片的，一个当前窗体的，只要判断当前窗体的矩形是否被背景图片的矩形包含就能判断背景图片是否出界原理是一样的啊，你把人物图片也new一个矩形出来，矩形的左上角坐标就是人物左上角的坐标，长和宽就是人物图片的长和宽，然后同理new一个窗体的矩形出来。判断人物的矩形是不是被窗体的矩形包含，包含就表示没有出界。Rectangle(矩形)这个类是有一个方法contains直接比较的。

还有一点就是建议你移动的时候不要立即修改坐标，先搞一个零时变量来记录移动后的位置，用这个位置去做比较，如果没有出界再去修改真实的坐标。

我用JAVA写好了一个窗体游戏，怎么加背景音乐？

java怎么将一个游戏程序窗口在自定义的窗口里运行

一、选择项目右键导出

二、选择java - JAR file - next

三、选择导出路径

四、下一步

五、选择Swing程序，入口frame

六、点击Finish，jar文件导出成功。

紧急！！！用java做一个小游戏有窗口的。。

将以下代码保存为MainFrame.java JDK1.6编译通过

保存我没有做，也不难。方法我已经空下了，你可以自己写写试试.
