Fibonacci Series 

   
class FibonacciExample1
{
  public static void main(String args[])
  {  
      int n1=0,n2=1,n3,i,len=10;  
      System.out.print(n1+" "+n2);//printing 0 and 1  

      for( i=2 ; i < len ; ++i )
      {  
        n3=n1+n2;  
        System.out.print(" "+n3);  
        n1=n2;  
        n2=n3;  
      }  
  }
}

Output : 

0 1 1 2 3 5 8 13 21 34
