java编程，设计一个窗体，要有三个部分（文本框、按钮、标签），按钮内容输出到文本框

package anfang;

import java.awt.*;

import java.awt.event.*;

public class example1 extends Frame{

Frame frm;

Button btn1,btn2,btn3,btn4;

TextField txt1,txt2,txt3;

public example1()

{

setLayout(null);

btn1 = new Button("+");

btn1.setLocation(55,55);

btn1.setSize(80,20);

class BtnClick implements ActionListener

{

public void actionPerformed(ActionEvent e)

{

txt3.setText(""+(Integer.parseInt(txt1.getText())+Integer.parseInt(txt2.getText())));

}

}

BtnClick bc=new BtnClick();

btn1.addActionListener(bc);

add(btn1);

btn2 = new Button("-");

怎样用JAVA编程编写题目：设计一个窗体，在窗体中有个按钮，单击退出按钮，窗体消失

/** 希望 对你有用 同学 一个简单而 但 很 实用的例子 */import java.awt. * ;

import java.awt.event. * ;import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.SwingUtilities;public class swing extends JFrame { /**

* @param args

*/

JFrame j;

public swing() {

j = new JFrame("close windows");

j.setBounds(100, 100, 100, 100); // 设置 窗体 大小

j.getContentPane().setLayout(new FlowLayout(ABORT)); //设置 布局

JButton jbtn = new JButton();

jbtn.setText("退出");

jbtn.addMouseListener(new MouseAdapter(){ // 鼠标 监听 按下

public void mouseClicked(MouseEvent e) {

// TODO Auto-generated method stub

System.exit(0);

super.mouseClicked(e);

}

});

j.add(jbtn); // 按钮添加到 窗体

j.setVisible(true); // 设置窗体 可见

}

public static void main(String[] args) {

SwingUtilities.invokeLater(new Runnable(){

public void run() {

// TODO Auto-generated method stub

new swing();

}

});
