简单 取消数组重复元素 的问题？急急急！！！

Question

下面是两个数组，UserName()   和   Score()  
  现在要把每个用户的的分之和   给每一位用户，  
  即重新生成两个新的数组，  
  比如结果因该是：  
                xing   共得分   xxx  
                xingworld   共得分   xxx  
                Richardmax   得分   xxx  
   
  用尽量简练的语言怎么做，谢谢！ 二个数组别为:
UserName="xing,   xingworld,   xingworld,   xingworld,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   xing,   Richardmax,   xing,   xing,   xing,   xing,   xing,   Richardmax,   Richardmax,   Richardmax,   Richardmax,   Richardmax,   Richardmax,   Richardmax"  
   
  WinScore="1,   2,   3,   4,   5,   6,   7,   8,   9,   10,   11,   12,   13,   14,   15,   16,   17,   18,   19,   20,   21,   22,   23,   24,   25,   26,   27,   28,   29,   30,   31,   32,   33,   34,   35,   36"用java类来实现或javascript都可?

Answer 1

用HashMap存储，key为用户名，value为得分
将上述数据遍历一遍后即可

Answer 2

我给你写了一个方法 你可以试一下，add（）的第一个参数是姓名的数组，第二个参数是分数的数组；package test;public class SplitAdd {
  public SplitAdd() {
  }
  public String[] userName;  //新数组存储三个人的姓名
  public int[] winScore;   //新数组存储三个人的总成绩
  
  public void add(String[] user,int[] score){
    int xingScore=0;
    int xwScore=0;
    int rcmScore=0;
    for(int i=0;i<user.length;i++){
       String name = user[i];
       if(name.equals("xing")){
         xingScore = xingScore + score[i];
       }
       if(name.equals("xingworld")){
         xwScore = xwScore + score[i];
       }
       if(name.equals("Richardmax")){
         rcmScore = rcmScore + score[i];
       }
    }
    //为新数组添加三个人的名字
    this.userName[0] = "xing";
    this.userName[1] = "xingworld";
    this.userName[2] = "Richardmax";
    //为新数组添加三个人的总成绩
    this.winScore[0] = xingScore;
    this.winScore[1] = xwScore;
    this.winScore[2] = rcmScore;
    
  }
}

Answer 3

你可以在这个类里 添加你自己的main（）函数，我没给你加，你加上自己测试一下吧，祝你成功！
