In this program, we are going to share a Java program to check palindrome string using Queue. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a Java program to check palindrome string using Queue.
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.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | 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."); } } |
Enter any string:xyzzyx
xyzzyx
The input String is a palindrome.
