Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Use TicketCounter to demonstrates the use of a queue for simulating a line of customers(use java).
For the Queue use the java interface Queue with the ArrayDeque classFor the Stack use the java Deque interface with the ArrayDeque classFor the LinkedList, use the java LinkedList class Also, when you are asked to create and use a Queue, you can use only those methods pertaining to the general operations of a queue (Enqueue: addLast, Dequeue: removeFirst, and peek() Similarly, when you are asked to create and/or use a stack, you can use only those methods pertaining to the general operations of a Stack (push: addFirst, pop:removeFirst, and peek() ) Your code should not only do the job, but also it should be done as efficiently as possible: fast and uses no additional memory if at all possible Questions Write a method “int GetSecondMax(int[] array)” . this method takes an array of integers and returns the second max value Example: if the array contains: 7, 2, 9, 5, 4, 15, 6, 1}. It should return the value: 9
Given the queue myData 12, 24, 36 (front is 12), what is the result of the following operations? Enqueue(myData, 48)Enqueue(myData, 60)Dequeue(myData)print(Peek(myData))print(IsEmpty(myData))
