Take Two - Java File Reading

I got the bare basics working (see SVN ) but wanted to try storing words for later...

Version 2.0 <-CLK IT:

• gives Total word count
• gives unique word count
• stores words in hashtable --(currently re-evaluating this decision... not sold)

Main Differences:

• It runs.
• Imported only required header files
• Stores words in Hashtable if unique

Primary In-Class Difficulties :

• Lack of Java programming experience
• Main Issue = how to compile and run???
• javac FILENAME.java
• java FILENAME          //NO '.java' HERE!!!!!!
• Unfamiliar with Classes/Data structures/Variables/ Java Quirks
• Examples:
• must include Boolean (not a given like in c++)
• .java file needs to be a class, not just have main

Later Difficulties :

Nouns and Verbs - Data structures and Algorithms

•  How to store the data?
• I want to find the most commonly used words - I want a hierarchy, not just a single string-value pair (<-boring)
• Considered Hash tables
• How do I index or access in any order when my keys are non-numeric? Enum, but...eh. Shouldn't it be simpler?
• Considering Vector of String-Int pairs
• Could methodically insert
• How to sort the data?
• Algorithms
• Heap sort? Merge sort? Some....Sort? 
• n log(n)  for heap/merge

Version Three : The SORT-o-MATIC - coming soon to a blog near you.
