Question

java编写程序实现对于任意整型数组元素的随机乱序例子

Answer 1

/**
* 打乱指定数组的顺序，并返回该数组
* @param array
* @return
*/
public int[] randomArray(int[] array){
Random rand = new Random();
for(int i=1;i<=array.length*100;i++){
int left = rand.nextInt(SIZE*SIZE-1);
int right = rand.nextInt(SIZE*SIZE-1);
if(left != right){
int temp = array[left];
array[left] = array[right];
array[right] = temp;
}
}
return array;
}
