Fibonacci Series Using Java With I/O Stream

In this blog, you will learn about the Fibonacci series in Java programs, using 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;
  }
 }
}
