Question
6.X2
DRAW (by hand) an object diagram with:
TheaterCorp object named myCorp
corpName of ”United Movies”
the following Movie elements in the movies HashSet field:
movies.add(new Movie(“Bambi”, Rating.G))
movies.add(new Movie(“Jumanji”, Rating.PG))
movies.add(new Movie(“DieHard”, Rating.R))
the following Theater elements in the theaters ArrayList field:
1st element location is”Pitman” with the following screens HashMap elements:
screens.put( 1 , )
screens.put( 2 , )
2nd element location is”Glassboro” with the following screens HashMap elements:
screens.put( 1 , )
screens.put( 2 , )
NOTE: Make sure the HashMap Movie references à the same Movie objects in the HashSet
I Dont know the Solutions
6.X3
WRITE only ONE line of code using chaining to return the location of the 2ndTheater element in the theaters field for the above project (NOTE: Assume that all the elements do indeed exist)
WRITE the result of this statement execution given the current state from object diagram in 6.X2
6.X4
WRITE ONE line of code using chaining to return the title of the Movie playing on screens with key 1 of the 1st element in the theaters field for the above project
WRITE the result of this statement execution given the current state from object diagram in 6.X2
6.X5
WRITE ONE line of code using chaining to return the Rating String representation of the Movie playing on screens with key 1 of the 2nd element in the theaters field for the above project
WRITE the result of this statement execution given the current state from object diagram in 6.X2

Create a "New Class..." named Driver to start execution of a project whose current state is presented in Exercise 6 X2 and thereby depicted by the object diagram drawn there MUST include ONLY a main method with proper header and body contents CHECK your work by calling mycorp.listAllTheaterMovies ()to ensure terminal output matches the following: May also CHECK the solutions and results of your Exercises 6 X3-6.X5 by using println statements here in your main method to testExplanation / Answer

screen= 3--Die Hard (R)
Glassboro
screen= 1--Bombie (G)
screen= 2--Jumanji (PG)
screen= 3--Die Hard (R)
to retrieve the rating
moviename Bombie---rating G
moviename Jumanji---rating PG
moviename Die Hard---rating R
