Classes Quiz Practice
This quiz will primarily focus on ArrayLists, classes, interfaces and GridWorld. There may be other material on there as well. You should be very comfortable defining a simple class, answering questions about Bug, implementing an interface and doing ArrayList manipulations.
Here are some practice problems. Also refer to the multiple choice practice set.

Review of Comparable
Comparable — Location — note that this asks you to implement the Comparable<Location> interface, which means that your compareTo method will take an Location as a parameter. You should be comfortable with implementing the Comparable interface and having compareTo take in an Object as a parameter.
Comparable — Point — same note as above
Oracle interfaces questions and exercises — these are all great review with solutions
