java jframe radio选择性别

您可以使用JRadioButton来实现性别的单选选择，以下是一个简单的示例代码：

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

public class GenderSelection extends JFrame {
    private JRadioButton maleRadioButton, femaleRadioButton, otherRadioButton;
    private ButtonGroup genderButtonGroup;

    public GenderSelection() {
        setTitle("Gender Selection");
        setLayout(new FlowLayout());

        JLabel genderLabel = new JLabel("Select your gender:");
        add(genderLabel);

        maleRadioButton = new JRadioButton("Male");
        femaleRadioButton = new JRadioButton("Female");
        otherRadioButton = new JRadioButton("Others");

        genderButtonGroup = new ButtonGroup();
        genderButtonGroup.add(maleRadioButton);
        genderButtonGroup.add(femaleRadioButton);
        genderButtonGroup.add(otherRadioButton);

        add(maleRadioButton);
        add(femaleRadioButton);
        add(otherRadioButton);

        pack();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setVisible(true);
    }

    public String getSelectedGender() {
        if (maleRadioButton.isSelected()) {
            return "Male";
        } else if (femaleRadioButton.isSelected()) {
            return "Female";
        } else {
            return "Others";
        }
    }

    public static void main(String[] args) {
        GenderSelection genderSelection = new GenderSelection();
        String selectedGender = genderSelection.getSelectedGender();
        System.out.println("Selected gender: " + selectedGender);
    }
}

您可以在main函数中创建GenderSelection对象，并通过调用getSelectedGender方法来获取用户选择的性别。
