冒泡排序java

如题冒泡排序：

public class paixu{public void sort(int[] arr){System.out.print("排序前：");for(int m : arr){System.out.print(m + " ");}int temp ;for (int i = arr.length - 1;i > 0;i--){System.out.print("\n第" + (arr.length - i) + "趟排序: ");for (int j = 0; j < i; j++){if(arr[j] > arr[j + 1]){temp = arr[j + 1];arr[j + 1] = arr[j];arr[j] = temp;};}for(int m : arr){System.out.print(m + " ");}}}public static void main(String[] args){int[] arg = new int[]{9,3,2,5,6,4,8,1,7};new paixu().sort(arg);}}
