title: Groovy - Type testing?
body: <p>I'm really brand new to Groovy and I'm trying to get something done. I've written some Groovy code (which works just fine) which receives some text. This text should be an integer (between 0 and 10). It may just happen a user enters something different. In that case I want to do some specific error handling.</p>
  
  <p>Now I'm wondering, what's the best / grooviest way to test if a string-typed variable can be casted to an integer? </p>
  
  <p>(what I want to do is either consume the integer in the string or set the outcome of my calculation to 0.</p>
  
  <p>Thanks!</p>
