Java program to check palindrome string using Queue with the output

Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.

import java.util.Queue;
import java.util.Scanner;
import java.util.LinkedList;

class PalindromeExample {

    public static void main(String[] args) {

    	System.out.print("Enter any string:");
        Scanner in=new Scanner(System.in);
        String inputString = in.nextLine();
        Queue queue = new LinkedList();

        for (int i = inputString.length()-1; i >=0; i--) {
            queue.add(inputString.charAt(i));
        }

        String reverseString = "";

        while (!queue.isEmpty()) {
            reverseString = reverseString+queue.remove();
        }
        if (inputString.equals(reverseString))
            System.out.println("The input String is a palindrome.");
        else
            System.out.println("The input String is not a palindrome.");

    }
}

import java.util.Queue;

import java.util.Scanner;

import java.util.LinkedList;

class PalindromeExample {

public static void main(String[] args) {

System.out.print("Enter any string:");

Scanner in=new Scanner(System.in);

String inputString = in.nextLine();

Queue queue = new LinkedList();

for (int i = inputString.length()-1; i >=0; i--) {

queue.add(inputString.charAt(i));

}

String reverseString = "";

while (!queue.isEmpty()) {

reverseString = reverseString+queue.remove();

}

if (inputString.equals(reverseString))

System.out.println("The input String is a palindrome.");

else

System.out.println("The input String is not a palindrome.");

}

Program Output

Enter any string:xyzzyx
xyzzyx
The input String is a palindrome.
