输入两个单独的整数，它们之间没有空格？

我正在制作一个彩票游戏，我想知道是否有办法输入两个整数，例如 3 和 4，但将它们输入为 34 并让它们单独读取？我需要让它们单独阅读，因为如果输入的数字之一与随机生成的数字之一匹配，游戏就会奖励。到目前为止，我的代码是这样的：

import java.util.Scanner;
import java.util.Random;

public class Lottery {

   public static void main(String[] args) {

   Scanner keyboard = new Scanner(System.in);
   Random random = new Random();

   int guess, guess2, counter;
   int win1000, win10, win1;

   int number = random.nextInt(10); int number2 = random.nextInt(10);
   System.out.println("Welcome to the Super Lottery! \nLet's Play!");
   System.out.println("Round 1 - you have 5 chances to win money");

   System.out.print("Enter your guess: ");
   guess = keyboard.nextInt(); 
   guess2 = keyboard.nextInt();
   System.out.println("The lottery number is " + number + number2);

   win1 = 1;
   win10 = 10;
   win1000 = 1000;

   counter = 1;
   while(counter < 5) {
      number = random.nextInt(10); number2 = random.nextInt(10);
      System.out.print("Enter your guess: ");
      guess = keyboard.nextInt(); guess2 = keyboard.nextInt();
      System.out.println("The lottery number is " + number + number2);
      counter++;

   if(guess == number2 && guess2 == number) {
      System.out.println("You guessed both numbers, but in a different order! You win $" + win10);  
   }
   else if(guess == number && guess2 == number2) {
      System.out.println("CONGRATULATIONS! You win the Super Lottery!" + win1000);
   }
   else if(guess == number || guess2 == number2) {
       System.out.println("You guessed one number! You win $" + win1);
   }
   }

   }
}

由于 random.nextInt 有 10 作为参数，这意味着随机生成的数字将从 0 到 9。

话虽如此，我将假设玩家将输入的数字是从 00 到 99。

您可以为此使用字符串，然后将其拆分为两部分。

检查此代码示例：

 Scanner keyboard = new Scanner(System.in);
 String number = keyboard.nextLine();
 int guess, guess2;
 guess = Integer.valueOf((number.substring(0, 1)));
 guess2 = Integer.valueOf((number.substring(1, 2)));
 System.out.println(guess);
 System.out.println(guess2);
