用JAVA创建和打印用户列表

public class User {
    private String name;
    private int age;
    private String gender;

    public User(String name, int age, String gender) {
        this.name = name;
        this.age = age;
        this.gender = gender;
    }

    // Getters and setters

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }
}

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<User> userList = new ArrayList<>();

        // 添加用户对象到列表
        userList.add(new User("张三", 25, "男"));
        userList.add(new User("李四", 30, "女"));
        userList.add(new User("王五", 28, "男"));

        // 打印用户列表
        for (User user : userList) {
            System.out.println("姓名：" + user.getName());
            System.out.println("年龄：" + user.getAge());
            System.out.println("性别：" + user.getGender());
            System.out.println("--------------------");
        }
    }
}
