我有两个数组, 想拿出两个数组中不同的数字_JAVA_编程开发_程序员俱乐部

我有两个数组,｛1,3,2,5,6,8},{7,4,9,1,5}
想取出这两个数组中不同的数字,
                
                String []s1=  { "1","3","2","5","6","8"};
                 String []s2=  {"7","4","9","1","5"};
                 for(int i=0;i<s1.length;i++){
                         for (int j = 0; j < s2.length; j++) {
                                 if(s1[i] != s2[j]){
                                         System.out.println(s1[i]);
                                 }
                         }
                 }

        上面是我写的,    运行后显示不一样的数字每个都显示了5遍,    能不能只显示一遍？
