Java program to check whether string is palindrome using library methods

public class StringPalindromeJava
{
   public static void isPalindrome(String str)
   {
      String strReverse = new StringBuffer(str).reverse().toString();
       // checking for palindrome
      if(str.equals(strReverse))
      {
         System.out.println(str + " is palindrome string.");
      }
      else
      {
         System.out.println(str + " is not palindrome string.");
      }
   }
   public static void main(String[] args)
   {
      // palindrome java
      isPalindrome("eye");
      isPalindrome("rotator");
   }
}

Java program to check palindrome number using recursion

// Java program to check palindrome number using recursion
public class PalindromeNumberRecursion
{
   static int palindromeRecursion(int number, int temp)
   {
      if(number == 0)
         return temp;
      // storing reverse of a number
      temp = (temp * 10) + (number % 10);
      return palindromeRecursion(number / 10, temp);
   }
   public static void main(String[] args)
   {
      int number = 141;
