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;

}

}

已经给楼主写好了...祝楼主早日成功哈!!!!!

用java编写四个类。用户类（User）角色类（Role ） 权限类(Right)测试类(test)

程序如下：

class User{

private String userName;

private String passWord;

private Role role;

public User(String userName, String passWord, Role role){

this.userName = userName;

this.passWord = passWord;

this.role = role;

}

public Role getRole() {

return role;

}

public String getUserName() {

return userName;

}

}

class Role{

private int roleId;

private String roleText;

private String users;

private Right rights;

public Role(int roleId, String roleText, String users, Right rights){

this.roleId = roleId;

this.roleText = roleText;

this.users = users;

this.rights = rights;

}

public int getRoleId() {

return roleId;

}

}

class Right{

private int rightId;

private String rightText;

private String roles;

public Right(int rightId, String rightText, String roles){

this.rightId =rightId;

this.rightText= rightText;

this.roles = roles;

}

}

public class Test {

public static void main(String[] args) {

Right rights = new Right(2013012701, "banana", "host");

Role role = new Role(20130127, "apple", "Zhang San", rights);

User user = new User("Zhang San", "zhangsan123", role);

System.out.println("The ID of user: " + user.getUserName() + "'s role is " + (user.getRole()).getRoleId());

}

}
