Palindrome Program in Java using Recursion

Interview Preparation

In this tutorial you will learn how to write a program in Java to check a given number is palindrome or not using recursion.

Before moving directly on the writing the program to check whether a given number is palindrome or not using recursion

 

Read This: What is Palindrome Number? Write a palindrome program in C using recursion.

How this Java program will behave?

This Palindrome program will take a integer as an input. After applying some operation which is written in program it will print output.

Suppose if someone gives an input 1441 then our program should print “the given number is a palindrome”.

And if someone given input 1234 the our program should print “the given number is not a palindrome number”.

Java program for palindrome number using recursive method

import java.util.*;  
class Main{
    static int sum=0,rem;
    static int isPalindrome(int num)
    {
        if(num == Main.reverse(num))
        {
            return 1;
        }
    return 0;
    }
    
    static int reverse(int num){
       if(num!=0){
            rem=num%10;
            sum=sum*10+rem;
            reverse(num/10);
        }
        else
            return sum;
        return sum;
    }

    public static void main(String ...args){
        int result;
        Scanner sc= new Scanner(System.in);
        System.out.print("Enter number- ");  
        int originalNum= sc.nextInt();  
        result = Main.isPalindrome(originalNum);
        if(result == 1){
            System.out.println("number is a palindrome");
        }else{
            System.out.println("number is not a palindrome");
        }
    }
}

Output:

java program to check Number is palindrome or not using recursion
