Testing the Methods That Remove Strings

Testing remove and clear

Our class BagOfStrings is essentially complete. Since we have tested all methods except remove and clear, we assume that they are correct. The program BagDemo3 removes strings from an empty bag, a full bag, and a bag that is neither empty nor full. In addition to the methods addToBag and displayBag from our earlier tests, BagDemo3 defines another method—removeFromBag—that removes a given string from a given bag. If the given string is null, the method will call our first remove method that removes one unspecified string from the bag. Otherwise, it will remove the given string.
