In this exercise, you’ll implement a generic PriorityQueue<T> class that is parameterized by the type of object it contains. The priority queue will be used as a container of objects of type T. Implement Priority Queue in the following three ways

Create a small console application which provides a demo of various operations and its effect on the PriorityQueue object. There is no need for the application to be user interactive.

you are creating a small game for school kids. Game has multiple steps:

1Display following message to user: “Enter any number from 1-5"

2User enters an option from 1-5, show the exact message to user for the number selected

1Enter even number

2Enter odd number

3Enter a prime number

4Enter a negative number

5Enter zero

for e.g. if user has selected 1, then show “Enter even number”,

If user does not enter correct number from 1-5 show error message. and then -> GOTO step 1

3.If user has entered correct number, then show success, else show error. -> after this GOTO step 1

To validate type of user input, there should be a validation method, which will return true if user input is correct, else validation method will throw different exception for different failure scenario.

Create a CustomException class.

Also, when user has played this game for 5 times, show a message to user you have played this game for 5 times. Handle this also using exception.
