Question

我做了一个简单的猜测游戏，但我不知道怎么问玩家是否想再次玩游戏。每次游戏结束我都要再次运行游戏所以我想要添加此功能。我查看了其他一些帖子，但他们没有帮助。这是代码：

import java.util.*;
public class guessNumber{
private static Scanner userInput = new Scanner(System.in);
public guessNumber(){
    System.out.println("~~~Guess Game~~~");
}
public void guessGame(){
System.out.println("Enter the maximum number:");
int maxNum = userInput.nextInt();
System.out.println("Guess a number between 0 and " + maxNum + ":");
    int randomNumber = (int) (Math.random() * maxNum);
    boolean gameOn = true;
    int numberOfTries = 0;
    while(gameOn){
    boolean printOthers = true;
    numberOfTries++;
    int number = userInput.nextInt();
    if(number > maxNum){
        System.out.println("Please enter a number between 0 and " + maxNum + ".");
        printOthers = false;
        }
    if(printOthers){
    if(number == randomNumber){
        System.out.println("=================================");
        System.out.println("You guessed the right number xD.");
        System.out.println("Your tried " + numberOfTries + " times.");
        System.out.println("=================================");
    }else if(number > randomNumber){
        System.out.println("Try a lower number");
    }else if(number < randomNumber){
        System.out.println("Try a higher number");
    }
    else{
        System.out.println("Please enter a number between 0 and " + maxNum + ".");
    }
    }
}

}
    public static void main(String[] args){
    guessNumber guess = new guessNumber();
    guess.guessGame();




}
}

Answer 1

在你的主要使用while循环。在循环中首先调用你的guessGame（）然后，类似于你要求输入一个数字，你问他们是否想要再次玩（Y / N？），如果他们说不，你就打破了循环，否则你继续...

Answer 2

使用while循环在main方法中添加调用方法

public static void main(String[] args){
 Scanner scanner = new Scanner(System.in);
do{
//call your game
System.out.println("Do you want to play again. Press y");
}
while(scanner.next().equals("y"));
