Simple Java program for Palindrome

This program is simplified for easy understanding using the StringBuilder with reverse function in java.

import java.util.Scanner;

public class Palindrome {

public static void main(String args[]){

//Get the string to check 

System.out.println("Enter the string: ");

Scanner sc = new Scanner(System.in);

String inp = sc.nextLine();

sc.close();

//String to string builder to store in heap

StringBuilder sb = new StringBuilder();

sb.append(inp);

//Reverse function over the string 

sb = sb.reverse();

String temp = sb.toString();

//compare to check Palindrome

if (inp.equals(temp)){

System.out.println("The given string is a Palindrome.");

}else{

System.out.println("The given string is not a Palindrome.");

}

}

}

Output:

Enter the string: madam

The given string is a Palindrome.

Enter the string: Rajesh

The given string is not a Palindrome.
