一道基础的数组应用问题

Question

1.写出一个用户实体类UserEntity：
public class UserEntity 
{
private String userId;
private String userName;
private String userPwd;
private String realName;
private int age;
private String cellPhone;
private String email;

public String getUserId() 
{
return userId;
}
public void setUserId(String userId) 
{
this.userId = userId;
}
public String getUserName() 
{
return userName;
}
public void setUserName(String userName)
{
this.userName = userName;
}
public String getUserPwd() {
return userPwd;
}
public void setUserPwd(String userPwd) 
{
this.userPwd = userPwd;
}
public String getRealName() 
{
return realName;
}
public void setRealName(String realName)
{
this.realName = realName;
}
public int getAge() 
{
return age;
}
public void setAge(int age)
{
this.age = age;
}
public String getCellPhone()
{
return cellPhone;
}
public void setCellPhone(String cellPhone) 
{
this.cellPhone = cellPhone;
}
public String getEmail() 
{
return email;
}
public void setEmail(String email) 
{
this.email = email;
}
}这部分没问题，关键是下面的：
写出一个数据仓库模拟类，要求属性包括用户实体数组，构造方法要初始化用户实体数组，至少5个用户信息。我完全绕不过弯啊！求指点

Answer 1

package net.csdn.test;public class UserFactory { private UserEntity[] entryArr; public UserFactory() { // 1st user
UserEntity ue1 = new UserEntity();
ue1.setAge(26);
ue1.setCellPhone("88888888");
ue1.setEmail("[email protected]");
ue1.setRealName("RealName");
ue1.setUserId("8888");
ue1.setUserName("UserName");
ue1.setUserPwd("UserPwd"); // 2nd user
UserEntity ue2 = new UserEntity();
ue2.setAge(26);
ue2.setCellPhone("88888888");
ue2.setEmail("[email protected]");
ue2.setRealName("RealName");
ue2.setUserId("8888");
ue2.setUserName("UserName");
ue2.setUserPwd("UserPwd"); // 3rd user
UserEntity ue3 = new UserEntity();
ue3.setAge(26);
ue3.setCellPhone("88888888");
ue3.setEmail("[email protected]");
ue3.setRealName("RealName");
ue3.setUserId("8888");
ue3.setUserName("UserName");
ue3.setUserPwd("UserPwd"); // 4th user
UserEntity ue4 = new UserEntity();
ue4.setAge(26);
ue4.setCellPhone("88888888");
ue4.setEmail("[email protected]");
ue4.setRealName("RealName");
ue4.setUserId("8888");
ue4.setUserName("UserName");
ue4.setUserPwd("UserPwd"); // 5th user
UserEntity ue5 = new UserEntity();
ue5.setAge(26);
ue5.setCellPhone("88888888");
ue5.setEmail("[email protected]");
ue5.setRealName("RealName");
ue5.setUserId("8888");
ue5.setUserName("UserName");
ue5.setUserPwd("UserPwd"); entryArr = new UserEntity[] { ue1, ue2, ue3, ue4, ue5 };
}

public static void main(String[] args) {

UserFactory uf = new UserFactory();
System.out.println(uf.entryArr[0].getEmail());
}
}

Answer 2

class UserEntity{
 private int[] ids;
 private String[] names;
 private String[] passwords;
 public UserExtity(int id,String nama,String password){
  ids=Array.copyOf(ids,ids.length+1);
  ids[ids.length-1]=id;
  names=Array.copyOf(names,names.length+1);
  names[names.length-1]=name;
  passwords=Array.copyOf(passwords,passwords.length+1);
  passwords[passwords.length-1]=passwords;
 }
}
难道是这样，我很迷茫

Answer 3

UserEntity[] arry=new UserEntity[] (new UserEntity(),new UserEntity()，new UserEntity()，new UserEntity()，new UserEntity()) ; 只要一个实例的话这样就可以

Answer 4

接上面的问题，package User;
import java.util.Scanner;
public class UserManager
{
public static void main(String[] args) 
{
DbStore abc = new DbStore();

Scanner input = new Scanner(System.in);
System.out.println("请输入用户名：");
String name = input.next();
System.out.println("请输入密码：");
String password = input.next();

if((abc.entryArr()[i].userName!= name)||(abc.entryArr()[i].userPwd != password))
{
System.out.println("用户不存在或密码错误！");
}
else
{
System.out.println("该用户的真实姓名为"+abc.entryArr()[i].realName);
}
}
}
这段话也有错。为什么！if语句后面的entryArr
