Lexical Density Analyzer

Objective

Build your problem-solving skills by creating a new analyzer! The LexicalDensityAnalyzer class is capable of calculating the lexical density of a given text file. Lexical density is a measure of the ratio of lexical (content) words to the total number of words in a text.

Instructions

Create a new analyzer, named LexicalDensityAnalyzer in the Analyzer application.

LexicalDensityAnalyzer Class Purpose

  • The purpose of the LexicalDensityAnalyzer class is to calculate the lexical density of a file and output the results along with the list of lexical words used.

  • What does it know? - for you to determine!

  • What does it do? - for you to determine!

LexicalDensityAnalyzer Class Details

  • To understand lexical density, review this resource: http://www.analyzemywriting.com/lexical_density.html.
  • Using the definitions and examples of lexical density in the article above, add a LexicalDensityAnalyzer to calculate and output lexical density.
  • The output report can be of your own design.
  • Write your own unit tests (test drive class or classes to prove that each method of your lexical density analyzer works). You do not need to use jUnit.
    • For example, one test might should verify that "john smith intensely loves going to the huge cinema everyday" has an 80% lexical density.
