$1.$ Write a Java program that represents a queue data structure to simulate a queue of customers waiting to a grocery checkout line.

Implement the queue using Java queue interface by linkedlist.

Print menu with numbers and description as follows:

$1.$ Insert

$2.$ Remove

$3.$ Peek

$4.$ Check Empty

$5.$ Check Full

$6.$ Size

Then scan the number insert by the user and apply the function related to the number. Each function

should have print in last line to print out the results.

After that the program should ask user if like continue or not. If $$Yes$$ is answer, then show again the

above menu and wait for user. Otherwise, if the response from user is $$No$$ then exit the program.
