palindrome java method code example

Example 1: 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");
   }
}

Example 2: palindrome in java

package com.candidjava; import java.util.Scanner; public class PalindromeUptoN{	public static void main(String[] args)	{		int n, b, rev = 0;		Scanner sc = new Scanner(System.in);		System.out.println("Enter the Palindrome No N:");		int N = sc.nextInt();		System.out.print("Palindrome numbers from 1 to N:");		for (int i = 1; i <= N; i++)		{			n = i;			while (n > 0)			{				b = n % 10;				rev = rev * 10 + b;				n = n / 10;			}			if (rev == i)			{				System.out.print(i + " ");			}			rev = 0;		}	} }
