公司培训，老师给了一组斐波那切让自己理解，但是真心看不懂，贴出来求大哥大姐帮忙看看指点一二。
public static void main(String[] args) {                                         
         int numbers = fibonacci(5);                    
          System.out.println(numbers);                  
         }  
          public static int fibonacci(int fbnq){         
           if(fbnq<=1) {                                 
               return 1;
           }
           return fibonacci(fbnq-1)+fibonacci(fbnq-2);
           }
        }

谢谢版主提醒，那天也是没招了，发帖子之后的半天就要问到，太捉急，感谢讲解得这么详细
