#### Example 1: Program to Check Palindrome using while loop

public class Palindrome { public static void main(String[] args) { int num = 121, reversedInteger = 0, remainder, originalInteger; originalInteger = num; // reversed integer is stored in variable while( num != 0 ) { remainder = num % 10; reversedInteger = reversedInteger * 10 + remainder; num /= 10; } // palindrome if orignalInteger and reversedInteger are equal if (originalInteger == reversedInteger) System.out.println(originalInteger + " is a palindrome."); else System.out.println(originalInteger + " is not a palindrome."); } }

**Output**

121 is a palindrome number.

#### Example 2: Program to Check Palindrome using for loop

public class Palindrome { public static void main(String[] args) { int num = 11221, reversedInteger = 0, remainder, originalInteger; originalInteger = num; // reversed integer is stored in variable for( ;num != 0; num /= 10 ) { remainder = num % 10; reversedInteger = reversedInteger * 10 + remainder; } // palindrome if orignalInteger and reversedInteger are equal if (originalInteger == reversedInteger) System.out.println(originalInteger + " is a palindrome."); else System.out.println(originalInteger + " is not a palindrome."); } }

**Output**

11221 is not a palindrome.
