Method Detail

getWords

public Set<Word> getWords()

Provide the words of a phrase. Each word may have to be cleaned up: punctuation removed, put into lower case

equals

public boolean equals(Object o)

The behavior of this lab depends on how you view this method. Are two phrases the same because they have the same words? Or are they the same because they are string-equlivalent.

• What song, Is that Becky
• What song is that, Becky

The above phrases have the same words but are different strings.

Overrides:

equals in class Object

hashCode

public int hashCode()

This method must also be properly defined, or else your HashSet structure won't operate properly.

Overrides:

hashCode in class Object

cleanUp

protected static String cleanUp(String s)

Filter the supplied String (which is the String of a Phrase presumably) into a canonical form for subsequent matching. The acutal filtering depends on what you consider to be insignificant in terms of matching.

• If punctuation is irrelevant, remove puncutation.
• If case does not matter, than convert to lower (or upper) case.

toString

public String toString()

Overrides:

toString in class Object
