A pаlindrоme is а sequence thаt reads the same fоrward and backward. In this prоblem, you will determine if a sequence of financial transactions, stored in a LinkedList, is a palindrome based on the transaction amounts. You are given a Transaction class that stores a unique transactionId and a double amount. Your task is to write a static method, isTransactionPalindrome, that checks if the sequence of transaction amounts in a given LinkedList forms a palindrome. Use the PalindromeChecker class as a template for your solution. After your program runs successfully, upload image of the execution.    class Transaction {    private String transactionId;    private double amount;    public Transaction(String transactionId, double amount) {        this.transactionId = transactionId;        this.amount = amount;    }    public double getAmount() {        return this.amount;    }    @Override    public String toString() {        return "ID: " + transactionId + ", Amount: " + amount;    }}import java.util.LinkedList;import java.util.Queue;import java.util.Stack;import java.util.Iterator;public class PalindromeChecker {    /**     * Checks if the sequence of transaction amounts in a LinkedList forms a palindrome.     *     * @param transactions The list of transactions to check.     * @return true if the sequence of amounts is a palindrome, false otherwise.     */    public static boolean isTransactionPalindrome(LinkedList transactions) {        // A list with 0 or 1 element is always a palindrome.        if (transactions.size()
