设计一个用户类(User),类中变量有用户名、口令和用户个数的变量(赋值、为用户名和口令赋值),获取和设置口令的方法和返回类信息的方法
public class User {
private String user_name; //用户名称
private String user_password;//用户口令
private static int user_count=0; //统计用户个数
//设置getter、setter方法
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getUser_password() {
return user_password;
}
public void setUser_password(String user_password) {
this.user_password = user_password;
}
public static int getUser_count() {
return user_count;
}
public static void setUser_count(int user_count) {
User.user_count = user_count;
}
//定义构造方法(无参、单参、全部参数)
public User() {
this("无名氏","111111");
}
public User(String user_name) {
this(user_name,"111111");
}
public User(String user_name,String user_password) {
this.user_name =user_name;
this.user_password = user_password;
user_count++;
}
//获取用户个数
public static String getCount() {
return "用户个数为:"+user_count;
}
//获取用户相关信息
public String getInfo() {
return "【用户信息】用户名:"+user_name+"用户口令:"+user_password;
}
//主方法测试
public static void main(String[] args) {
User userA = new User();
User userB = new User("小花");
User userC = new User("大花","111111");
System.out.println(userA.getInfo());
System.out.println(userB.getInfo());
System.out.println(userC.getInfo());
System.out.println(User.getCount());
}
}
