利用swing控件创造界面

『壹』 如何使用java+swing开发一个界面

用Frame或者Jframe做都行。

『贰』 使用Swing组件构建图形用户界面，实现秒表计时程序。

你这个完全不用别人来帮忙，JDK自带的例子就有。
比如JDK安装目录下的demos\Java2D就有好多动画的可以参考，比你这还复杂。
你这个用个java timer应该就可以搞定。

『叁』 使用Java swing组件设计如下图像界面程序

import java.awt.event.MouseEvent;

import java.awt.event.MouseListener;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JPasswordField;

import javax.swing.JTextField;

public class test extends JFrame {

public static void main(String[] args) {

test test = new test();

}

private JButton submit,cancel;

private JLabel password,username,info;

private JTextField textusername;

private JPasswordField textpassword;

public test() {

super("login");

super.setSize(300, 200);

super.setVisible(true);

super.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

this.setLocationRelativeTo(null);

this.init();

this.addinfo();

this.setLayout(null);

this.repaint();

}

//初始化界面

void init()

{

username = new JLabel("用户名：");

username.setBounds(10, 10, 80, 20);

this.add(username);

textusername = new JTextField();

textusername.setBounds(90,10,150,20);

this.add(textusername);

password = new JLabel("密码：");

password.setBounds(10, 40, 80, 20);

this.add(password);

textpassword = new JPasswordField();

textpassword.setBounds(90,40,150,20);

this.add(textpassword);

submit = new JButton("登 录");

submit.setBounds(60,80,60,20);

this.add(submit);

cancel = new JButton("取消");

cancel.setBounds(130,80,60,20);

this.add(cancel);

info = new JLabel("请输入用户名和密码");

info.setBounds(90, 100, 150, 20);

this.add(info);

}

//加入监听器

void addinfo() {

submit.addMouseListener(new MouseListener() {

@Override

public void mouseReleased(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mousePressed(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseExited(MouseEvent e) {

}

@Override

public void mouseEntered(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseClicked(MouseEvent e) {

//用户名密码比较

if(textusername.getText().equals("123")&&textpassword.getText().equals("123"))

{

info.setText("用户名密码正确");

}

else

{

info.setText("用户名密码错误");

}

}

});

cancel.addMouseListener(new MouseListener() {

@Override

public void mouseReleased(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mousePressed(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseExited(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseEntered(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseClicked(MouseEvent e) {

textusername.setText("");

textpassword.setText("");

}

});

}

}

『陆』 .分别使用swing组件和awt组件创建图1所示界面(两个文本和三个按钮).(注意:不需要提供任何功能)图中第二题

这么简单的题自己都不作

『柒』 java swing组件实现类似于 桌面图标 的界面。

你是想干什么 设置背景图片？如果只是要设置背景图片可以先放在Jpanel里 然后再加到 Jframe 里。
jdk里好像没有针对窗口改变的listener

如果对您有帮助，请记得采纳为满意答案，谢谢！祝您生活愉快！

『捌』 java swing怎样开发出漂亮的界面

Swing 支持切换界面风格啊...
默认的是Metal风格,确实不好看
你可以切换为Windows风格,看起来和Windows上的程序就是一样滴了,还可以切换为苹果的风格,很Beauty滴说.
如果你用的是jdk6,甚至可以自己定义自己想要的风格.
一句话,用Swing做界面,只有想不到,没有做不到.

『玖』 分别使用swing组件和awt组件创建图1所示界面(两个文本和三个按钮).(注意:不需要提供任何功能)你之前问的题

大哥，能不能把图传上来
