编写程序,读取在 1 到 100 之间的整数,然后计算每个数出现的次数。假定输入是以 0 结束的。
下面是这个程序的一个运行示例:
Write a program that reads the integers between 1and 100 and counts the occurrences of each. Assume the input ends with 0.Note that if a number occurs more than one time, the plural word“times”is used
in the output.
Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0
2 occurs 2 times
3 occurs 1 time
4 occurs 1 time
5 occurs 2 times
6 occurs 1 time
23 occurs 1 time
43 occurs 1 time
下面是参考答案代码:

import java.util.Scanner;
public class Ans7_3_page236 {public static void main(String[] args) {int[] number = new int [101];
Scanner input = new Scanner(System.in);
int num;
System.out.print("Enter the integers between 1 and 100:");
do {num = input.nextInt();
number[num] = number[num] + 1;
}
while (num != 0);
for (int i = 1; i < number.length; i++) {if (number[i] == 1) {System.out.println(i + "occurs" + number[i] + "time");
}else if (number[i] > 1)
System.out.println(i + "occurs" + number[i] + "times");
}
}
}
