Chcek whether a number is a Palindrome or not in java code example
Example 1: easy palindrome program in java
import java.util.*;
class PalindromeExample2
{
public static void main(String args[])
{
String original, reverse = "";
Scanner in = new Scanner(System.in);
System.out.println("Enter a string/number to check if it is a palindrome");
original = in.nextLine();
int length = original.length();
for ( int i = length - 1; i >= 0; i-- )
reverse = reverse + original.charAt(i);
if (original.equals(reverse))
System.out.println("Entered string/number is a palindrome.");
else
System.out.println("Entered string/number isn't a palindrome.");
}
}
Example 2: palindrome number in java
import java.util.Scanner;
public class Palindrome
{
public static void main(String args[])
{
int num,temp,reverse=0;
Scanner input=new Scanner(System.in);
num=in.nextInt();
temp=num;
while(temp!=0)
{
int d=temp%10;
reverse=reverse*10+d;
temp/=10;
}
if(reverse==num)
{
System.out.println("Number is palindrome");
}
else
{
System.out.println("Number is not palindrome");
}
}
}
