如果有人按e，我希望我的游戲在游戲中隨時停止。import java.util.Scanner;public class Game { public static void main(String[] args) { Scanner input = new Scanner(System.in); int points = 0; int multiply; System.out.println("press e to exit the game at any time! "); System.out.println("please enter a number"); int yourNumber = input.nextInt(); for (multiply = 0; multiply<= 10; multiply++){ int yourAnswer = yourNumber * multiply; System.out.println(yourNumber + " x " + multiply + " = ? "); int theAnswer = input.nextInt(); for (int tries = 1; tries<= 4; tries++){ if (theAnswer == yourAnswer){ points = points + 5; System.out.println("you have " + points + " points"); break; } else{ System.out.println("Your answer : " + theAnswer + " is wrong, please try again. Attempts : " + tries + " out of 4"); theAnswer = input.nextInt(); points--; if (tries == 4){ System.out.println("sorry maximum attempts!!! moving to the next question"); tries++; break; } } } } }}

而不僅僅是“int theAnswer = input.nextInt();” 寫這個：
String nextIn = input.next();
int theAnswer = 0;
if (nextIn.equal("e")) {
System.out.println("Exiting the game...")
break;
}
else {
theAnswer = Integer.parseInt(nextIn);
}
顯然我沒有考慮到例外情況，但如果你愿意的話也可以。
總的來說，它看起來像這樣：
public class Game{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int points = 0;
int multiply;
System.out.println("press e to exit the game at any time!");
System.out.println("please enter a number");
int yourNumber = input.nextInt();
for (multiply = 0; multiply<= 10; multiply++){
int yourAnswer = yourNumber * multiply;
System.out.println(yourNumber + " x " + multiply + " = ? ");
//new part:
String nextIn = input.next();
int theAnswer = 0;
if (nextIn.equals("e")) {
System.out.println("Exiting the game...")
break;
} else {
theAnswer = Integer.parseInt(nextIn);
}
for (int tries = 1; tries<= 4; tries++){
if (theAnswer == yourAnswer){
points = points + 5;
System.out.println("you have " + points + " points");
break;
}
else{
System.out.println("Your answer : " + theAnswer + " is wrong, please try again. Attempts : " + tries + " out of 4");
theAnswer = input.nextInt();
points--;
if (tries == 4){
System.out.println("sorry maximum attempts!!! moving to the next question");
tries++;
break;
}
}
}
}
}
}
