Factorial Program Using Java With I/O Streams

Introduction

In this blog, I will explain about the Factorial 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 da
 {
  public static void main(String arg[]) throws IOException
   {
    DataInputStream d = new DataInputStream(System.in);
    int i,n,f;
    String s;
    f=1;
    System.out.print("enter the number : ");
   s = d.readLine();
    n = Integer.parseInt(s);
     for(i=1;i<=n;i++)
      {
        f = f * i;
      }
    System.out.println("\n"+"factorial of given number "+n+" is : " +f);
   }
 }
