Question

我为自己创建了一个简单的项目，现在我正在尝试集成一个代码，当我在控制台中输入“restart”时会使程序重新启动。为此，我在我的程序中创建了第二个方法，它包含与我的main方法完全相同的代码，但现在我想指定第二个方法，我不知道该怎么做。所有帮助表示赞赏！这是我目前的代码：

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    System.out.println("guess the number between 1 and 9");

    int random = (int)(Math.random() * 9 + 1);

    int value = 0;
    do{
        value = scanner.nextInt();

        if (value != random){
            System.out.println("Try again");
        }

    }


    while(value != random);

    System.out.println("You guessed the number");   

    if(value == random){
        System.out.println("Would you like to restart?");
        String reset = scanner.nextLine();
        if (reset.equals("restart")){
            /*
             *I need some code here

            */
        }
    }   
}

public static void restart(String[] args){

    Scanner scanner = new Scanner(System.in);

    System.out.println("guess the number between 1 and 9");

    int random = (int)(Math.random() * 9 + 1);

    int value = 0;
    do{
        value = scanner.nextInt();

        if (value != random){
            System.out.println("Try again");
        }

    }


    while(value != random);

    System.out.println("You guessed the number");   

    if(value == random){
        System.out.println("Would you like to restart?");
        String reset = scanner.nextLine();
        if (reset.equals("restart")){

        }
    }   
}

你应该在＆＃34中调用main（）; if（reset.equals（＆＃34; restart＆＃34;））{...＆＃34;

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    System.out.println("guess the number between 1 and 9");

    int random = (int)(Math.random() * 9 + 1);

    int value = 0;
    do{
        value = scanner.nextInt();

        if (value != random){
            System.out.println("Try again");
        }

    }


    while(value != random);

    System.out.println("You guessed the number");   

    if(value == random){
        System.out.println("Would you like to restart?");
        String reset = scanner.nextLine();
        if (reset.equals("restart")){
            main(args); // restart you code
            return;
        }
    }   
}

或使用以下代码：

public static void main(String[] args) {
  Scanner scanner = new Scanner(System.in);
  do{

    System.out.println("guess the number between 1 and 9");

    int random = (int)(Math.random() * 9 + 1);

    int value = 0;
    do{
        value = scanner.nextInt();

        if (value != random){
            System.out.println("Try again");
        }    
    } 
    while(value != random);

    System.out.println("You guessed the number");       
    System.out.println("Would you like to restart?");
    String reset = scanner.nextLine();
  } 
  while(reset.equals("restart")); 
}

尝试这样的事情，

在您的代码中，


你一直搞乱代码，需要按照要求分解，

此外，如果用户想要重新启动，则需要注意再次玩游戏。

通过以下代码克服了这一点，

static int value;
static int random  = (int)(Math.random() * 9 + 1);
static Scanner scanner = new Scanner(System.in);
public static void main(String[] args) {

    do{
        System.out.println("Enter Your Guesses :");
        value = scanner.nextInt();
        if(value == random){
            System.out.println("Exactly Match : " + value  + " == " + random);
            System.out.println("Would you like to restart?");
            String reset = scanner.next();
            if (reset.equals("restart")){
                restart();
            }
        }else{
            System.out.println("Try again");
        }

    }while(value != random);

    System.out.println("You guessed the number");   


}
public static void restart(){
    do{
        random = (int)(Math.random() * 9 + 1);
    }while(value == random);
}

在Java中指定方法
