    private String password;
    private String sex;
    private Integer age;

    public User(String name, String password, String sex, Integer age) {
        this.name = name;
        this.password = password;
        this.sex = sex;
        this.age = age;

                ", age='" + age + '\'' +
                '}';
    }

    public static void main(String[] args) {
        User [] users=new User[3];

        for (User user:users) {
            System.out.println(user);
        }
    }
}

public class User {
