Practice with Classes: Movie

1. Make a Movie class and a MovieTest class.
2. Static variables: ?
3. Instance variables: title, ... , ?
   1. Are there default values for these?
4. Constructors:
   1. Is a title required? Yes. Make it so using a constructor
   2. What other combination of parameters could be used to make a movie object?
5. Static methods:
6. Instance methods:
   Deciding which methods there are depends on the big picture of what you are doing with the movies:
   (i) possibly putting them into a playlist to play on a DVD player or video player,
   or (ii) programming a movie rental place.

To do: Make 3 or 4 movies using MovieTest.java
What would we name each Movie object?

Array lists : a nicer solution

• they are like arrays, but you can change the length as you go
• Some arraylist methods:
  ArrayList<Movie> movieCollection = new ArrayList<Movie>(); //make an array list of movie objects
arraylist.add(e); //adds element e at end
arraylist.add(i , e); //adds element e at position i
e = arraylist.get(i); //returns element at location

Other useful code:

m1 = new Movie("Moonrise Kingdom");
movieCollection.add(new Movie("Wrath of Khan"));
movieCollection.add(m1);	//adds to end

//Print out the list of movies use a for-each loop
for (Movie m : movieCollection) {
    System.out.println(m.toString());
}

To do: Can you print out only the titles of the movies?

This Movie.java and MovieTest.java will not be marked -- you just have to do them and I'll comment on them and correct them. I'll be marking the next assigment on bank accounts
