Using java program

Question

I have a set of documents. I want to know the frequency of each word in each document (i.e.) using a java program. thanks in advance. I know how to find the frequency for each word. My question is how to accept unique words in each document from the list of documents

Answer 1

You can divide your documents into spaces and punctuation, go through the resulting array and then calculate the frequency for each word (a Map<String, Integer>really helps you with that).
