You can count how may times the \n appears in the paragraph for lines.
For characters the total length of the paragraph String minus the characters: " ", " ", " ", ...
For words user String.split(" "); and count the length of the array minus the elements where you might an empty String with more than one length.

Or you can use regular expressions.

Yes that is a good way to do it. but when you do that you could use StringTokenizer class. it seperates a string to tokens. just change the delimeters to count sentences , lines ,words etc. I hope that could help.

note:
every sencence finish with "."
every line finish with "\n"
every word finish with "\n" , " " , "." or ","

Well my approach would be simple, Buffered reader to read in from file, We will use java's inbuilt Hash Map class to store words, and also to count number of occurrences. Then we bubble sort the words and print top ten words, sounds simple isn't it?

please find complete working source code here.
