Как попросить пользователя продолжить?

Question

Я сделал этот код, и все работает нормально, но я бы хотел, чтобы пользователь нажал кнопку ввода, чтобы продолжить показ, пока они не выиграют или не проиграют. Любые предложения были бы замечательными.

Answer 1

В java вы должны использовать Scanner. Вы можете увидеть, как его использовать здесь How can I read input from the console using the Scanner class in Java?

Answer 2

Я бы сказал, вместо того, чтобы код, встроенный в основной, имел другой метод, в конце этого метода вы спрашиваете пользователя, хотят ли они снова играть, а затем да, тогда метод вызывает себя снова рекурсивно, если не программа завершается, так что вы затем вызвать его в основной, например

public static void play() 
    { 
     //place code here 

    S.o.p("play again?"); 
    //if yes call itself to startover 
    play(); 
    //if no, program terminates 
    } 

Тогда в основной у вас есть только вызов метода

public static void main(String...args) 
    { 
     play(); 
    } 

это мое предложение.

Edit: чтобы избежать потока stackover я обеспечиваю альтернативное

public static void play() 
    { 
     //place code here 
    } 

    public boolean playAgain(int choice) 
    { 
     if(!choice==1) 
     return false; 

    Return true; 
    } 

    public staic void main(String...args) 
    { 
    int repeat =0; 
     do 
     { 
     play(); 
     S.o.p("play again?\n enter 1 for yes,0 for no"); 
     //assign repeat the number choice 
     }while(playAgain(repeat)); 
    } 

Примечания: код предполагает правильный ввод от пользователя.
