JAVA Program to Check a Palindrome String ~ Codext | C, C++, C#,JAVA Programming Tutorials

To find out whether a given String is a Palindrome or not is among one of the very basic problems of coding in various languages including JAVA, C, C++ etc. A string is said to be Palindrome string if it has the beginning words and ending words same characters or we can also say that a Palindrome string is a string which may be read the same way in either direction i.e. from first character to last character or last character to first character.

JAVA Program to check Palindrome String

import java.util.*;

class Pal
{
   public static void main(String args[])
   {
      String original, reverse="";
      Scanner in = new Scanner(System.in);

      System.out.println("Enter a string to check if it is a palindrome");
      original = in.nextLine();

      int length = original.length();

      for ( int i = length - 1 ; i >= 0 ; i-- )
         reverse = reverse + original.charAt(i);

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

   }
}
