一道基础的数组应用问题
1.写出一个用户实体类UserEntity：

Java code

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

Java code

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("xxx@xxx.com");        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("xxx@xxx.com");        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("xxx@xxx.com");        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("xxx@xxx.com");        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("xxx@xxx.com");        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());    }}

class UserEntity{
  private int[] ids;
  private String[] names;
  private String[] passwords;
