删除数组中的重复元素

方案1：

用set也很容易的

public static void main(String[] args) {
       int[] nums = { 5, 6, 6, 6, 8, 8, 7 };
       List<Integer> numList = new ArrayList<Integer>();
       for (int i : nums)
           numList.add(i);
       Set<Integer> numSet = new HashSet<Integer>();
       numSet.addAll(numList);
       System.out.println(numSet);
   }

 

方案2：

public static void main(String[] args) {
        String[] s = {"1","10","15","14","111","133","12","13","1","13"};
        List<String> l = new ArrayList<String>();
        for(String a:s){
            if(!l.contains(a)){
                l.add(a);
            }
        }
        System.out.println(l);
    }
