0---130 统计一位数有多少个，三位数有多少个 ，10-19多少个 。。。。。90--99 多少个

public class Test2{public static void main(String[] args){int[] ages = new int[100];for (int i = 0; i < 100; i++){ages[i] = (int) (Math.random() * 130);}int s[] = new int[11];for (int i = 0; i < ages.length; i++){if (ages[i]/10==10){s[0]++;} else if (ages[i]/10<10){s[ages[i]/10]++;} else{s[10]++;}}int a = 0;for (int i = 0; i < s.length; i++){System.out.println(s[i]);a = a + s[i];} }}
