Class PointQueue

java.lang.Object

PointQueue

public class PointQueue
extends java.lang.Object

This is an implementation of a Queue in Java that uses a built-in data structure about which we haven't learned yet. You should assume that it works just like our Queues in OCaml. Each element in the queue is an array of two ints. This class will be useful to you when you write the flood() function in Manipulate.java. You do not need to modify this file.
