用java实现Windows10的计算器界面

实现Windows10的计算器界面需要使用Java GUI库，如Swing或JavaFX。以下是一个简单的示例程序：

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

public class Calculator extends JFrame {
    private JPanel panel;
    private JTextField textField;
    private JButton button0, button1, button2, button3, button4, button5, button6, button7, button8, button9;
    private JButton buttonAdd, buttonSub, buttonMul, buttonDiv, buttonEqual, buttonClear;

    public Calculator() {
        super("Calculator");

        textField = new JTextField(20);
        textField.setEditable(false);

        button0 = new JButton("0");
        button1 = new JButton("1");
        button2 = new JButton("2");
        button3 = new JButton("3");
        button4 = new JButton("4");
        button5 = new JButton("5");
        button6 = new JButton("6");
        button7 = new JButton("7");
        button8 = new JButton("8");
        button9 = new JButton("9");

        buttonAdd = new JButton("+");
        buttonSub = new JButton("-");
        buttonMul = new JButton("*");
        buttonDiv = new JButton("/");
        buttonEqual = new JButton("=");
        buttonClear = new JButton("C");

        panel = new JPanel();
        panel.setLayout(new GridLayout(4, 4, 5, 5));
        panel.add(button7);
        panel.add(button8);
        panel.add(button9);
        panel.add(buttonDiv);
        panel.add(button4);
        panel.add(button5);
        panel.add(button6);
        panel.add(buttonMul);
        panel.add(button1);
        panel.add(button2);
        panel.add(button3);
        panel.add(buttonSub);
        panel.add(button0);
        panel.add(buttonClear);
        panel.add(buttonEqual);
        panel.add(buttonAdd);

        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());
        contentPane.add(textField, BorderLayout.NORTH);
        contentPane.add(panel, BorderLayout.CENTER);

        setSize(300, 300);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        Calculator calculator = new Calculator();
        calculator.setVisible(true);
    }
}

这个程序使用了JFrame、JPanel、JTextField、JButton等Swing组件，通过setLayout()方法设置了布局方式，实现了Windows10的计算器界面。
