[java] store each word into a treemap
Author
I'm storing a line of text into an ArrayList like so:
basically, each word is stored into the ArrayList 'linesOfText' .
Since I want to create a treemap, how could I store all the words with the line numbers in a treemap?
Or, how could I get each word individually one by one?

If the line of text is separated by single spaces you could use this...
Documentation for String might also be useful. It does have a lot of helpful methods for making Strings easier to work with.
String line = document.readLine();String words[] = line.split(" ");Documentation for String might also be useful. It does have a lot of helpful methods for making Strings easier to work with.

mako, I want to be able to extract each word from ArrayList linesOfText in a new method instead.
sorry, wasn't thinking.
so you're indexing the lines where each word appears?
as in word->all line #'s where you can find this word
