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());
}
}
