java jframe 性别选择

您可以在JFrame中添加一个JComboBox或JRadioButton组来实现性别选择。以下是一个简单的示例代码，其中使用JComboBox实现性别选择：

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

public class GenderSelection extends JFrame {
    private String[] genders = {"Male", "Female", "Others"};
    private JComboBox<String> genderComboBox;

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

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

        genderComboBox = new JComboBox<>(genders);
        add(genderComboBox);

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

    public String getSelectedGender() {
        return (String) genderComboBox.getSelectedItem();
    }

    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。
