去除字符串中重复数据的另一种思路

 都知道set吧，它里面是不允许有重复元素的，所以新思路中就用到了它。

 

package com.test;

import java.util.Arrays;
import java.util.HashSet;
import java.util.Iterator;
import java.util.List;
import java.util.Set;

public class RemoveSame {

    /**
     * 字符串去重
     * @param args
     */
    public static void main(String[] args) {
        String[] same = {"a","a","a","b","b","b","c","c","c"};
        List list = Arrays.asList(same);
        Set set = new HashSet(list);
        Iterator ita = set.iterator();
        String[] removeSame = new String[set.size()];
        for (int i = 0; ita.hasNext(); i++) {
            removeSame[i] = (String) ita.next();
        }
    }

}
