java - Java中的三位数彩票程序

我刚刚开始介绍Java编程课程，所以我并不了解。我在获取彩票变量的中间数字时遇到麻烦。我使用int lotteryDigit1 = lottery / 100;和int lotteryDigit2 = lottery % 100;来获取第一个和最后一个数字，但是我很难获取中间的数字。

import java.util.Scanner;
public class Lottery {`enter code here`
    public static void main(String[] args) {

        //generate random lottery numbers
        int lottery = (int)(Math.random() * 100);



        //ask user to enter a 3 digit guess
        Scanner numbers = new Scanner(System.in);
        System.out.println("Please enter your lottery pick. Three Digits Only");
        int guess = numbers.nextInt();

        //digits for lottery
        int lotteryDigit1 = lottery / 100;

        int lotteryDigit2 = lottery % 100;


        //digits for guess
        int guessdigit1 = guess / 100;
        int guessdigit2 = guess % 100;

最佳答案

试试这个代码

int lottery = 123;
System.out.println(lottery);
System.out.println(lottery % 10);
System.out.println(lottery % 100 / 10);
System.out.println(lottery / 100);

输出

123
