import java.awt.*;

import javax.swing.*;
public class JCalculator extends JFrame implements ActionListener {
private static final long serialVersionUID = -169068472193786457L;

private class WindowCloser extends WindowAdapter {
//退出
public void windowClosing(WindowEvent we) {
System.exit(0);
}
}
int i;
//创建一个数组
private final String[] str = { "7", "8", "9", "/", "4", "5", "6", "*", "1",
"2", "3", "-", ".", "0", "=", "+" };

//新生成一个按钮数组，数组长度为str数组的长度
JButton[] buttons = new JButton[str.length];
//归零键
JButton reset = new JButton("CE");
//计算输出框
JTextField display = new JTextField("0");

public JCalculator() {
super("Calculator");
JPanel panel1 = new JPanel(new GridLayout(4, 4));
//循环计算器按钮
for (i = 0; i < str.length; i++) {
buttons[i] = new JButton(str[i]);
//将按钮依次添加到界面
panel1.add(buttons[i]);
}

JPanel panel2 = new JPanel(new BorderLayout());
//界面添加计算输出框
panel2.add("Center", display);
//界面添加归零按钮
panel2.add("East", reset);
getContentPane().setLayout(new BorderLayout());
//添加panel2在整体布局的上部
getContentPane().add("North", panel2);
//添加panel1在整体布局的中间
getContentPane().add("Center", panel1);

for (i = 0; i < str.length; i++)
//为计算按钮添加监听
buttons[i].addActionListener(this);
//为归零按钮按钮添加监听
reset.addActionListener(this);
//为计算输出框添加监听
display.addActionListener(this);
addWindowListener(new WindowCloser());

//设置窗体大小为800*800
setSize(800, 800);
//显示为true显示，false为隐藏
setVisible(true);
pack();
}
//方法不全
public void actionPerformed(ActionEvent e) {
Object target = e.getSource();
String label = e.getActionCommand();
if (target == reset)
handleReset();
else if ("0123456789.".indexOf(label) > 0)

追问

还有一部分呢

可以注释完吗？

^﹏^

注释完就一定采纳哦～～ 嘿嘿

在么？？？

追答

行行注释？我只大概知道你这个代码是画计算器的，你代码本身都不全的，不好注释

追问

现在全了哦，就是

OK注释完了
