title: Reading a txt file, and putting each word into an array, without punctuation or numbers
body: <p>I am wondering how I would read a txt file with Java, and put each word from the txt file into a different bucket in an array, but without punctuation or numbers that are in the file. I'm only interested in storing the words.</p>
  
  <p>So if the text file contained: "25 chickens crossed the road." the program should create an array like {"chickens", "crossed", "the", "road"}</p>
  
  <p><strike>I would like to do this on a fairly large text file. Will I run into any run time issues?</strike></p>
  
  <p>If you could explain it to me like I'm a complete noob, that would be great.
  I appreciate it.</p>
