For this week's lab, you will use two of the classes in the Java Collection Framework: HashSet and TreeSet. You will use these classes to implement a spell checker. Set Methods For this lab, you will need to use some of the methods that are defined in the Set interface. Recall that if set is a Set, then the following methods are defined: set. size() -- Returns the number of items in the set. set. add(item) -- Adds the item to the set, if it is not already there. set. contains(item) -- Check whether the set contains the item. set. isEmpty() -- Check whether the set is empty. You will also need to be able to traverse a set, using either an iterator or a for-each loop. Reading a Dictionary The file words. txt (in the code directory) contains a list of English words, with one word on each line. You will look up words in this list to check whether they are correctly spelled. To make the list easy to use, you can store the words in a set. Since there is no need to have the words stored in order, you can use a HashSet for maximum efficiency.
