Homework 6 (The Rotating Dead) FAQ
Q: What are some good resources or examples I can look at to get started on this program?
A: Look at the lecture slides and the
TreeSet example from Friday's lecture.
If you want to read more about implementing AVL trees, see Chapter 4 of the Weiss textbook.
Q: Does my
HvZPlayer class still need to have an
hashCode method from HW4?
hashCode method will probably not be used.
equals is still important, and in general, when you override
equals, you should override
You won't be graded on methods outside of
compareTo, but we recommend that you leave in the methods you wrote in HW4.
Q: What is a
Why are the methods I need to write in this assignment declared as
Shouldn't they be
public so that the client can call them?
Should I declare all of my fields as
protected field can be seen by the class in which it is declared, along with any subclasses and classes in the same package.
The methods in this assignment are
protected because the abstract superclass has already written the
public methods and you don't need to write those.
You are overriding the
protected helper methods that the client is using to recursively implement the adding and removing operations on the tree.
The client will call the abstract class's
public method, which will then call your
protected method as a helper.
In terms of fields, no, you should not declare your fields as
protected on this assignment.
Fields should almost always be
private except in rare cases.
