**Assignment: Implementing a Priority Queue for Chores**

Objective: Write a class with a main method that uses a priority queue to store a list of chores, along with each chore’s priority. The goal is to manage chores by their urgency.

Instructions:
- You need to store the name of the chore and its assigned priority.
- Assigned priorities can be any positive integer. The exact prioritization structure (e.g., lower numbers indicate higher priority) is left for you to determine.
- Implement the solution using the Java Linked List Class to construct your priority queue.

Additional Notes:
- Ensure that the program is efficient in adding chores and retrieving them based on their priority.
- Consider scenarios in which multiple chores share the same priority and how to manage them.

This exercise aims to enhance understanding of priority queues and their practical application in organizing tasks based on importance.

You may use the Java Library Queue class for Part 2

Write a program to simulate checkout lines at a grocery store. There will be multiple queues, one for each checkout line. For this exercise, you may assume there are 5 checkout lines. You can use an array of queues to simulate the checkout lines.

Use the following logic:
1. Generate 5 customers and enqueue them, one customer in each queue.
2. Each new customer ready to check out chooses the shortest line.

Customers enter the checkout queues randomly, and then each time a customer is generated that customer chooses the shortest line. If the lines are equal, then the first available line is chosen. Each transaction takes a random amount of time to complete. Print each action taken with Queue number, to the display.

For your output show the queues with customers and activity, showing changes in each queue.

You can capture all of the output at the end of the program running. The program should list actions that have been performed and Queue numbers.

Be sure to limit your program in order to ensure that it does not run forever.
