Write a java program to checks whether a given string is a palindrome or not

Java program to checks whether a given string is a palindrome or not

In this program, we learn to chacks whether a given string is a palindrome or not.

Algorithm: Palindrome or not in Java

1. import java.util.*;
2. Create: class Palind{
3. Create main function: public static void main(String args[]){
4. String original, reverse=””;
5. Scanner in = new Scanner(System.in);
6. Print message “Enter a string to check if it is a palindrome”
7. Read string: original = in.nextLine();
8. Find length: int length = original.length();
9. for ( int i = length – 1 ; i >= 0 ; i– )
   1. reverse = reverse + original.charAt(i);

10. if (original.equals(reverse)) {

11. System.out.println(“Entered string is a palindrome.”);

12. else:  System.out.println(“Entered string is not a palindrome.”);

Source Code: Palindrome or not

import java.util.*;

class Palind
    {
        public static void main(String args[])
    {
    String original, reverse = "";
    Scanner in = new Scanner(System.in);

    System.out.println("Enter a string 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 is a palindrome.");
    else
    System.out.println("Entered string is not a palindrome.");

    }
    }

Expected Output:
