Fibonacci Series Using Java With I/O Stream

Introduction

In this blog, I will explain about a Fibonacci series program, using Java I/O stream. It is very simple in Java programming. The output will be displayed in the Run module.

Software Requirement

JDK1.3.

Simple program

import java.io.*;

class fib
 {
   public static void main(String arg[]) throws IOException
    {
      int f1=-1,f2=1,f3,i,n;

      String s = new String();

      DataInputStream dr = new DataInputStream(System.in);

      System.out.println("emter the number : ");

      s = dr.readLine();

        n=Integer.parseInt(s);

           for(i=0;i<n;i++)
            {
              f3 = f1+f2;
                System.out.println(f3);
                  f1=f2;
                  f2=f3;
            }
      }
  }
