java - Java中main()的表达式错误非法启动？

public class BottlesOfBeer {
  public static void countdown(int bottles) {
    if (bottles > 0) {
      System.out.printf("%d bottles of beer on the wall,\n", bottles);
      System.out.printf("%d bottles of beer,\n", bottles);
      System.out.printf("ya' take one down, ya' pass it around,\n", bottles);
      bottles -= 1;
      System.out.printf("%s bottles of beer on the wall.\n", bottles);
    } else if (bottles == 0) {
      System.out.println("No bottles of beer on the wall,");
      System.out.println("no bottles of beer,");
      System.out.println("ya' can't take one down, ya' can't pass it around,");
      System.out.println("'cause there are no more bottles of beer on the wall!");
    } else {
      System.out.println("Wait, you can't have negative bottles...");
    }

  public static void main(String args[]) {
    int bottles = 99;
        countdown(bottles);
      }
    }

Error: illegal start of expression [Line: 18]

我是Java的新手，我不明白为什么在编译时会收到此错误。该程序原本从99倒数到1，然后在酒瓶= 0时再次打印。

最佳答案

您没有关闭countdown方法，这使得main方法成为其中的一部分。在main方法上方添加结束}。

感谢您让我想起手动计算括号的日子。
