写出完整的java程序，实现一个有按钮的窗口，按钮名字为“请点击”。要怎么写？

我这里有个最基本的用法，你可以参考一下

import java.awt.*;
import java.awt.event.*;

public class TestA extends Frame {
	Button bt = new Button("请点击");
	TestA() {
		setLayout(null);
		// 关闭窗口
		this.addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				System.exit(0);
			}
		});
		setBounds(200, 100, 200, 200);
		setTitle("小窗口");
		setVisible(true);
		bt.setBounds(50,50,40,20);
		add(bt);
	}
	public static void main(String[] args) {
		new TestA();
	}
}

import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
import textedit.MainFrame;
public class click extends JFrame {
private JButton clickButton = new JButton();
public click() {
try {
jbInit(); // 初始化文本编辑器
} catch (Exception e) {
e.printStackTrace();
}
this.addWindowListener(new WindowAdapter() { // 添加监听
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
this.setSize(600, 600);
this.setVisible(true);
}
public static void main(String[] args) {

click click = new click(); // 声明Frame
}
private void jbInit() throws Exception {
clickButton.setText("请点击我");
clickButton.setSize(10,10);
this.add(clickButton);
}
}
