title: java regex to find words in string finds empty strings in symbols like .,!(? and empty space
body: <p>This is my case string:</p>
  
  <pre>"This is a test.  How many???  " + "Senteeeeeeeeeences are here... there should be 5!  Right?"</pre>
  
  <p>using 
  <code>String[] words = getText().split("[( +)!.?,]");</code></p>
  
  <p>I get this array:
  <code>[This, is, a, test, , , How, many, , , , , Senteeeeeeeeeences, are, here, , , , there, should, be, 5, , , Right</code></p>
  
  <p>How can I eleiminate empty strings?</p>
