数组随机打乱

int[] aa = {1,3,63,54,2,67};

把以上数组的值随机打乱

 

public class Test{

  public static void main(String[] args){

     int len = aa.length;

    int temp = 0;

   for(int i=0;i<len;i++){

      int ramdom = new Random().nextInt(len);

     temp = aa[i];

     aa[i] = aa[ramdom];

     aa[ramdom] = temp;

}

 

 }

}
