public static void main(String[] args) {int[] num = {6,5,9,8,45,2,3,55,1};//Arrays.sort(num);for (int i = 0; i < num.length-1; i++) {for (int j = i+1; j < num.length; j++) {if(num[i]>num[j]){int temp = num[i];num[i] = num[j];num[j] = temp;System.out.println(Arrays.toString(num)+"-----"+i);}}}}

打印结果：
