check.java

本源码主要是上课时所做实验

class  Fa
{
  float fa(int n)
  {     float a;
       if(n==0||n==1)
          {
           a=1;
           return a;
          }
       else
      {a=fa(n-1)+fa(n-2);
          
         return a;
       }
   }
}
public  class Check
{
  public static void main(String args[])
 {
       Fa x=new Fa();
       System.out.println(x.fa(10));     

       System.out.println(x.fa(100));
  }
}
