Find out Factorial of a Given Number - with and with out Recursion

Here is output :

With Out Recursion

Out Put is as following :

import java.io.*;
class FactorialWithoutRecursion
{
public static void main(String args[]) throws IOException
{
int i, product=1;

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the Number : ");
int n=Integer.parseInt(br.readLine());

System.out.print("Factorial of " + n + " is.. ");
for(i=n;i>=1;i--)
{
if(i!=1)
{
System.out.print(i + " * ");
}
else
{
System.out.print(i );
}
product=product*i;
}
System.out.println(" = " + product);
}
}

With use of Recursion:

Out Put is as following :

import java.io.*;
class Factorial
{
// this is a recursive function
int fact(int n)
{
int result;
if(n!=1)
{
System.out.print(n+" * ");
}
else
{
System.out.print( n );
}
if(n==1) return 1;

result = fact(n-1) * n;
return result;
}
}
class FactWithRecursion
{
public static void main(String args[]) throws IOException
{
int r;
Factorial f = new Factorial();
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the Number : ");
int n=Integer.parseInt(br.readLine());
System.out.print("Factorial of "+ n +" is " );
r=f.fact(n);
System.out.print(" = "+r);
}
}

String given as command line argument is Palindrome or not

Check String given as command line argument is Palindrome or not?

Out Put is as following :

import java.util.*;

class Palindrome
{
public static void main(String args[])
{
String originalString, reverseString="";

originalString = args[0];

int length = originalString.length();

for ( int i = length - 1 ; i >= 0 ; i-- )
reverseString = reverseString + originalString.charAt(i);

if (originalString.equals(reverseString))
System.out.println("Entered string is a palindrome.");
else
System.out.println("Entered string is not a palindrome.");

}
}

Fibonacci Series using Java.

Out Put is as following :

class FibonacciSeries
{
public static void main(String args[])
{
int PrevNum, NextNum, Sum, i;
PrevNum=NextNum=1;
System.out.println();
for(i=1;i<=10;i++)
{
System.out.print(PrevNum+" ");
Sum=PrevNum+NextNum;
PrevNum=NextNum;
NextNum=Sum;
}
