java设计一个表示用户的User类

public class Use {
public static void main(String args[]){
User user1=new User();
user1.setUsername("joyce717533");
user1.setPassword("千总四级");
System.out.println("user1:"+user1.toString());
User user2=new User("joyce717533");
user2.setPassword("千总四级");
System.out.println("user2:"+user2.toString());
User user3=new User("joyce717533","千总四级");
System.out.println("user3:"+user3.toString());

}
}

class User {
public String username;

public String password;

public static int record;

public User() {

}
public User(String username){
this.username=username;
}
public User(String username,String password){
this.username=username;
this.password=password;
}

public String getPassword() {
return password;
}

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

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}
public String toString(){
return "username: "+username+",passwrod: "+password;
}
}
