数组实现排序以及最大最小数字

public class MaxAndMin { public static void main(String[] args) { int flag1 = 0; int flag2 = 0; int[] date = { 313, 89, 123, 323, 313, 15, 90, 56, 39 }; for (flag1 = date.length - 1; flag1 > 0; flag1--) { for (flag2 = 0; flag2 < flag1; flag2++) { if (date[flag2] < date[flag2 + 1]) { int temp = date[flag2]; date[flag2] = date[flag2 + 1]; date[flag2 + 1] = temp; } } } System.out.print("排序后数组为:["); for (int num : date) { System.out.print(num); if (num != date[date.length - 1]) { System.out.print(","); } } System.out.println("]"); System.out.println("最大数字为["+date[0]+"]"+"最小数字为["+date[date.length-1]+"]"); } }
