title: My program says identifier is expected
body: <p>I'm trying to make a string binary search program. Trouble is I don't remember a straight forward way to convert  a string array into a Integer array.</p>
  
  <p>I've written a long and complicated way to convert them. However Netsbeans is saying my string array identifier is expected.</p>
