Instructions

$($a$)$ Add the following private instance variables to the Movie class:

$$ An instance variable called title of type String.

$$ An instance variable called director of type String.

$$ An instance variable called year of type int.

$($b$)$ Add the following methods to the Movie class:

$$ A void method called initialize that takes two Strings and an int

as arguments, and uses those arguments to set the values of the title,

director, year instance variables.

$$ A void method called display that displays the title and director of the

movie followed by the year in parentheses. For example, if the title of the

movie is Blade Runner, the director is Ridley Scott and the year is $1982,$

it should display Blade Runner dir. Ridley Scott $(1982).$

$$ Accessor methods $($getters$)$ for each instance variable.

$$ Mutator methods $($setters$)$ for each instance variable.

$($c$)$ In the main function of your main class, remove the line that prints Hello

World to the output screen and then create a Movie object and perform the

following unit tests:

$$ Initialize the movie object with a title, director and year of your choice,

and display it$.$ Your output might look like this:

Testing initialize and display:

Blade Runner dir. Ridley Scott $(1982)$

$$ For each instance variable use the corresponding mutator to change the

value, then use the accessor to make sure that the value changed. Your

output for getTitle and setTitle might look like this:

Testing setTitle and getTitle:

getTitle returns: Blade Runner

calling setTitle with argument: Brazil

getTitle returns: Brazil

$($d$)$ Run the main program to see if the tests were successful.

$($e$)$ Add an equals method to the Movie class that takes a Movie object as anargument and returns true if the argument has the same title, director, and

year as the current object. Remember to use the equals method of the String class to compare the two titles.

$($f$)$ Add code in your main method in your main class that performs the following unit tests:

$$ Create two movies with different titles, but the same director and year,

and test if they are the same using equals. Your output might look like

this:

Testing equals on different titles, same director and

year

The Wasp Woman dir. Roger Corman $(1959)$

A Bucket of Blood dir. Roger Corman $(1959)$

equals returns false

$$ Create two movies with the same title and director, but different years

and test if they are the same using equals. Your output might look like

this:

Testing equals on different years, same title and

director

Halloween dir. John Carpenter $(1978)$

Halloween dir. John Carpenter $(2007)$

equals returns false

$$ Create two movies with the same title, director, and year, and test to see

if they are the same using both $==$ and equals. Your output might look

like this:

Testing equals and $==$ on objects with the same data

Suspiria dir. Dario Argento $(1977)$

Suspiria dir. Dario Argento $(1977)$

equals returns true

$==$ returns false

$$ Declare a variable of type Movie and set it equal to one of the previous

Movie objects you created. Compare the new variable and the one you

set it equal to using both $==$ and equals Your output might look like

this:

Testing equals and $==$ on references to the same object

Phantasm dir. Don Coscarelli $(1979)$

Phantasm dir. Don Coscarelli $(1979)$

equals returns true

$==$ returns true
