Смущение о выходе

Question

Я новичок в программировании на Java. Я просто начинаю читать первую первую Java-книгу. И я нашел этот пример в первой главе.

public class BeerSong { 
    public static void main(String[] args) { 
     int beerNum = 99; 
     String word = "bottles"; 
     while (beerNum > 0) 
     { 
      if (beerNum == 1) 
      { 
       word = "bottle"; 
      } 
      System.out.println(beerNum + " " + word + " of beer on the wall"); 
      System.out.println(beerNum + " " + word + " of beer"); 
      System.out.println("Take one down."); 
      System.out.println("Pass it around."); 
      beerNum = beerNum - 1; 
      if (beerNum > 0) 
      { 
       System.out.println(beerNum + " " + word + " of beer on the wall"); 
      } 
      else 
      { 
       System.out.println("No more bottles of beer on the wall"); 
      } 
     } 
    } 
} 

И я смущен о том, что вы ставите.

Как я понимаю код из пут следует начать с

99 bottles of beer 

потому int beerNum = 99;

Может кто-нибудь объяснить мне, почему я получаю выше выход начать с

60 bottles of beer 

Заранее спасибо. Мне было бы так здорово, если бы кто-нибудь мне это объяснил.

Answer 1

Да, выход должен начинаться с,

99 bottles of beer 

Нет ничего плохого в вашем коде. Как вы сказали, вы использовали Geany в качестве среды IDE. Geany использует командную строку для вывода вывода. Если вы используете eclipse или netbeans, вы получите правильный результат, как вы себе представляете.

Чтобы попытаться проверить будет изменить while (beerNum > 0) к чему-то вроде while (beerNum > 50) так, что она не производит так много выходных данных.

Answer 4

Вы правы, чтобы быть смущенным, поскольку код действительно выводит «99 бутылок пива ... и так далее».

Answer 5

Возможно, это связано с тем, что ваш выходной буфер консоли в вашей среде IDE достигнут, так что отображается только выход в пределах консоли.

Если вы используете затмение, то 1. Перейдите затмить предпочтение 2. Поиск консоли 3. Снимите флажок «Ограничить вывод консоли»

еще

Просто измените beerNum в какой-то меньшее значение (т.е. менее 50), и вы увидите полный вывод
