java实验题。。。。。。

2.设计一个 User 类，其中包括 ID 号、用户名、性别、年龄、密码、忘记 提醒等属性，且初始密码均为 111111。另外，还有注册、密码更改、用 户基本信息显示 3 个方法，构造方法中实现 ID 号的递增。编写应用程 序完成上述 User 类的测试。

User类

public class User {

    private static long id=0;
    private String name;
    private String sex;
    private int age;
    private String password;
    private String forget;

    public User() {
        super();
    }

    public User(String name, String sex, int age, String password, String forget) {
        super();
        this.id = getId()+1;
        this.name = name;
        this.sex = sex;
        this.age = age;
        this.password = password;
        this.forget = forget;
    }

    public static long getId() {
        return id;
    }

    public static void setId(long id) {
        User.id = id;
    }

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

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

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getForget() {
        return forget;
    }

    public void setForget(String forget) {
        this.forget = forget;
    }

    public User addUser(String name, String sex, int age, String password, String forget) {
        User user = new User(name, sex, age, password, forget);
        System.out.println(name+"创建成功");
        return user;
    }

    public void changePasswordById(long id,String newPassword){
        if (this.id==id) {
            this.password=newPassword;
            System.out.println("密码修改成功");
        }
    }

    public void showUserMsg(){
        System.out.println("用户Id"+this.id+"\t"+"用户姓名:"+this.name+"\t"
                +"用户性别"+this.sex+"\t"+"用户年龄"+this.age+"\t"+"用户密码:"+this.password);
    }

}

Test类

 public class Test {

    public static void main(String[] args) {
        User user = new User("张三", "男", 18, "123", "提醒");
        user.showUserMsg();
        User user2 = user.addUser("李四", "女", 20, "456", "提醒");
        user2.showUserMsg();
        user.changePasswordById(1, "789");
        user.showUserMsg();
    }
}
