利用java做一个计算器窗口，其功能实现加减乘除以及% sqrt log10

好的，我可以帮你实现这个功能。你需要创建一个 Java 项目，并且在项目中创建一个 Calculator 类。下面是一个实现加减乘除、%、sqrt、log10 功能的示例代码：

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

public class Calculator implements ActionListener {
    private JFrame frame;
    private JTextField numberField;
    private JButton addButton, subtractButton, multiplyButton, divideButton, modButton, sqrtButton, log10Button;
    private double result = 0;
    private String operator = "";

    public Calculator() {
        frame = new JFrame("Calculator");
        frame.setLayout(new FlowLayout());
        frame.setSize(300, 200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        numberField = new JTextField(10);
        frame.add(numberField);

        addButton = new JButton("+");
        addButton.addActionListener(this);
        frame.add(addButton);

        subtractButton = new JButton("-");
        subtractButton.addActionListener(this);
        frame.add(subtractButton);

        multiplyButton = new JButton("*");
        multiplyButton.addActionListener(this);
        frame.add(multiplyButton);

        divideButton = new JButton("/");
        divideButton.addActionListener(this);
        frame.add(divideButton);

        modButton = new JButton("%");
        modButton.addActionListener(this);
        frame.add(modButton);

        sqrtButton = new JButton("sqrt");
        sqrtButton.addActionListener(this);
        frame.add(sqrtButton);

        log10Button = new JButton("log10");
        log10Button.addActionListener(this);
        frame.add(log10Button);

        frame.setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        double number = Double.parseDouble(numberField.getText());

        if (e.getSource() == addButton) {
            result += number;
            operator = "+";
        } else if (e.getSource() == subtractButton) {
            result -= number;
            operator = "-";
        } else if (e.getSource() == multiplyButton) {
            result *= number;
            operator = "*";
        } else if (e.getSource() == divideButton) {
            result /= number;
            operator = "/";
        } else if (e.getSource() == modButton) {
            result %= number;
            operator = "%";
        } else if (e.getSource() == sqrtButton) {
            result = Math.sqrt(number);
            operator = "sqrt";
        } else if (e.getSource() == log10Button) {
            result = Math.log10(number);
            operator = "log10";
        }

        numberField.setText("");
    }

    public static void main(String[] args) {
        new Calculator();
    }
}

这个示例代码实现了一个简单的计算器窗口，包括一个文本框用于输入数字，以及加减乘除、%、sqrt、log10 等按钮。当用户点击按钮时，程序会根据按钮的功能进行相应的计算，并在文本框中显示结果。你可以根据自己的需求进行修改和扩展。
