In the lecture (unit1), we implement the concept of waiting list of generic type using an array.
1- Now, we want to implement the concept (as generic ) using ArrayList. Your generic WaitingList
class should include the following method:

1. a- add: it receives generic type elements and add it to the end of the list.
   
2. b- get: it receives an index and returns the element at the specific index (if there is ), or null if
   there is no such index.
   
3. c- remove: it removes the first element, and returns that element.
   
4. d- print: it prints the elements in the waiting list.
   

e- reverse: it reverses the order of the element in the list.
Create class GC_Test, that has main method. In the main,

1. a- Create WaitingList of Car, and add three cars.
   
2. b- Test method remove, reverse , and print the list after each method to test the methods.
   
3. c- Create WaitingList of Student, and add four students.
   
4. d- Test method remove, reverse , and print the list after each method to test the methods.
