java计算器含单选框实现进制转换

好的，我可以为您提供一个示例代码来实现这个功能。以下是Java计算器含单选框实现进制转换的示例代码：

import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ButtonGroup;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;

public class Calculator extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    private JTextField input, output;
    private JRadioButton binRadio, decRadio, hexRadio;
    private JButton[] numButtons = new JButton[16];
    private JButton addBtn, subBtn, mulBtn, divBtn, eqlBtn, clrBtn;

    public Calculator() {
        initUI();
    }

    private void initUI() {
        setTitle("Calculator");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 300);
        setLocationRelativeTo(null);

        JPanel contentPane = new JPanel(new FlowLayout());
        setContentPane(contentPane);

        JPanel topPanel = new JPanel(new GridLayout(2, 1));
        JPanel inputPanel = new JPanel(new FlowLayout());
        JLabel label = new JLabel("Input:");
        input = new JTextField(20);
        inputPanel.add(label);
        inputPanel.add(input);

        JPanel outputPanel = new JPanel(new FlowLayout());
        label = new JLabel("Output:");
        output = new JTextField(20);
        output.setEditable(false);
        outputPanel.add(label);
        outputPanel.add(output);

        topPanel.add(inputPanel);
        topPanel.add(outputPanel);

        JPanel radioPanel = new JPanel(new FlowLayout());
        binRadio = new JRadioButton("Binary");
        decRadio = new JRadioButton("Decimal");
        hexRadio = new JRadioButton("Hexadecimal");
        ButtonGroup group = new ButtonGroup();
        group.add(binRadio);
        group.add(decRadio);
        group.add(hexRadio);
        decRadio.setSelected(true);
        radioPanel.add(binRadio);
        radioPanel.add(decRadio);
        radioPanel.add(hexRadio);

        JPanel numPanel = new JPanel(new GridLayout(4, 4));
        for (int i = 0; i < 16; i++) {
            numButtons[i] = new JButton(Integer.toHexString(i).toUpperCase());
            numButtons[i].addActionListener(this);
            numPanel.add(numButtons[i]);
        }

        addBtn = new JButton("+");
        subBtn = new JButton("-");
        mulBtn = new JButton("*");
        divBtn = new JButton("/");
        eqlBtn = new JButton("=");
        clrBtn = new JButton("C");
        addBtn.addActionListener(this);
        subBtn.addActionListener(this);
        mulBtn.addActionListener(this);
        divBtn.addActionListener(this);
        eqlBtn.addActionListener(this);
        clrBtn.addActionListener(this);
        numPanel.add(addBtn);
        numPanel.add(subBtn);
        numPanel.add(mulBtn);
        numPanel.add(divBtn);
        numPanel.add(eqlBtn);
        numPanel.add(clrBtn);

        contentPane.add(topPanel);
        contentPane.add(radioPanel);
        contentPane.add(numPanel);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == clrBtn) {
            input.setText("");
            output.setText("");
            return;
        }

        String text = ((JButton) e.getSource()).getText();

        if ("+-*/".indexOf(text) >= 0) {
            input.setText(input.getText() + text);
            return;
        }

        int base = 10;
        if (binRadio.isSelected()) {
            base = 2;
        } else if (hexRadio.isSelected()) {
            base = 16;
        }

        try {
            int value = Integer.parseInt(input.getText(), base);
            output.setText(Integer.toString(value));
        } catch (NumberFormatException ex) {
            output.setText("Invalid input");
        }
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            Calculator calc = new Calculator();
            calc.setVisible(true);
        });
    }
}

这是一个简单的计算器，包含了单选框来选择进制，并且可以进行进制转换。您可以根据您的需要对代码进行修改和扩展。
