In this question, we will see how to input a number and check if it is a palindrome number or not in Java programming using while loop. To know more about while loop click on the while loop lesson.
Q14) Write a program in Java to input a number and check if it is a palindrome number or not using while loop.
Palindrome numbers are such numbers whose reverse is same as the original number. Example, 121, 14541, 22 etc.
Program
import java.util.Scanner;
public class Q14
{
public static void main(String args[])
{
int n,d,on,rev=0;
Scanner sc=new Scanner(System.in);
System.out.print("Enter any number ");
n=sc.nextInt();
on=n; // storing the original number
while(n>0)
{
d=n%10;
rev=(rev*10)+d; // reverse the number
n=n/10;
}
if(on==rev)
{
System.out.println("Palindrome Number");
}
else
{
System.out.println("Not Palindrome Number");
}
}
}Output
Enter any number 14541 Palindrome Number
