Java: Check if a positive number is a palindrome or not
Java Basic: Exercise-115 with Solution
Check Palindrome Number
Write a Java program to check if a positive number is a palindrome or not.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
public class test {
public static void main(String[] args) {
int num;
// Create a Scanner object for user input
Scanner in = new Scanner(System.in);
// Prompt the user for a positive integer
System.out.print("Input a positive integer: ");
// Read the integer entered by the user
int n = in.nextInt();
// Display a message to check if the number is a palindrome
System.out.printf("Is %d a palindrome number?\n", n);
// Check if the number is a palindrome and print the result
System.out.println(is_Palindrome(n));
}
// Function to reverse the digits of a number
public static int reverse_nums(int n) {
int reverse = 0;
while (n != 0) {
reverse *= 10;
reverse += n % 10;
n /= 10;
}
return reverse;
}
// Function to check if a number is a palindrome
public static boolean is_Palindrome(int n) {
return (n == reverse_nums(n));
}
}
Sample Output:
Input a positive integer: 151 Is 151 is a palindrome number? true
Flowchart:
Java Code Editor:
Previous: Write a Java program to given a string and an offset, rotate string by offset (rotate from left to right).
Next: Write a Java program which iterates the integers from 1 to 100. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". When number is divided by both three and five, print "fizz buzz".
