Java swing生成一个包括10个数字（0~9）按钮和4个运算符（加、减、乘、除）按钮，以及等号和清空两个辅助按钮，还有一个显示输入输出的文本框的计算器代码

好的，以下是用Java Swing实现一个简单的计算器的代码：

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

public class Calculator extends JFrame implements ActionListener {
    private JTextField inputField;
    private JButton[] numberButtons;
    private JButton[] operatorButtons;
    private JButton equalsButton, clearButton;
    private String currentDisplayValue = "";
    private String currentOperator = "";
    private double currentResult = 0.0;
    
    public Calculator() {
        setTitle("Calculator");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        
        inputField = new JTextField();
        inputField.setEditable(false);
        panel.add(inputField, BorderLayout.NORTH);
        
        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new GridLayout(4, 4));
        
        numberButtons = new JButton[10];
        for (int i = 0; i < 10; i++) {
            numberButtons[i] = new JButton(String.valueOf(i));
            numberButtons[i].addActionListener(this);
            buttonPanel.add(numberButtons[i]);
        }
        
        operatorButtons = new JButton[4];
        operatorButtons[0] = new JButton("+");
        operatorButtons[1] = new JButton("-");
        operatorButtons[2] = new JButton("*");
        operatorButtons[3] = new JButton("/");
        for (int i = 0; i < 4; i++) {
            operatorButtons[i].addActionListener(this);
            buttonPanel.add(operatorButtons[i]);
        }
        
        equalsButton = new JButton("=");
        equalsButton.addActionListener(this);
        buttonPanel.add(equalsButton);
        
        clearButton = new JButton("C");
        clearButton.addActionListener(this);
        buttonPanel.add(clearButton);
        
        panel.add(buttonPanel, BorderLayout.CENTER);
        
        setContentPane(panel);
        pack();
        setVisible(true);
    }
    
    public void actionPerformed(ActionEvent e) {
        for (int i = 0; i < 10; i++) {
            if (e.getSource() == numberButtons[i]) {
                currentDisplayValue += String.valueOf(i);
                inputField.setText(currentDisplayValue);
            }
        }
        
        for (int i = 0; i < 4; i++) {
            if (e.getSource() == operatorButtons[i]) {
                currentOperator = operatorButtons[i].getText();
                if (!currentDisplayValue.equals("")) {
                    currentResult = Double.parseDouble(currentDisplayValue);
                    currentDisplayValue = "";
                }
            }
        }
        
        if (e.getSource() == equalsButton) {
            if (!currentDisplayValue.equals("")) {
                double currentValue = Double.parseDouble(currentDisplayValue);
                if (currentOperator.equals("+")) {
                    currentResult += currentValue;
                } else if (currentOperator.equals("-")) {
                    currentResult -= currentValue;
                } else if (currentOperator.equals("*")) {
                    currentResult *= currentValue;
                } else if (currentOperator.equals("/")) {
                    currentResult /= currentValue;
                }
                currentDisplayValue = "";
            }
            inputField.setText(String.valueOf(currentResult));
        }
        
        if (e.getSource() == clearButton) {
            currentDisplayValue = "";
            currentOperator = "";
            currentResult = 0.0;
            inputField.setText("");
        }
    }
    
    public static void main(String[] args) {
        new Calculator();
    }
}

在代码中，我们使用了JFrame和JPanel来创建界面，使用JButton来添加按钮。同时，我们还使用了ActionListener来响应按钮的事件，实现了简单的计算功能。

注意在条件判断中通过getText()方法获取operatorButtons[i]按钮上的文本。
