Answer 1

Question:-

Design a class to input a number and print whether it is palindrome or not.

Program:-

In Java.

Using while loop.

import java.util.*;

class Palindrome

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter a number: ");

int n=sc.nextInt();

int m=n, s=0;

while(n!=10)

{

s=s*10+n%10;

n/=10;

}

if(s==m)

System.out.println("Palindrome.");

else

System.out.println("Not Palindrome. ");

}

}

Using for loop.

import java.util.*;

class Palindrome

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter a number: ");

int n=sc.nextInt();

int m=n, s=0;

for(;n!=10;n/=10)

s=s*10+n%10;

if(s==m)

System.out.println("Palindrome.");

else

System.out.println("Not Palindrome. ");

}

}
