title: How to use Split in report's expression
body: <p>Currently attempting to split a large string field into 3 smaller fields. The string delimited by a "/". Example String:</p>
  
  <pre><code>0123/ABCD1234/EFGH909883432212
  </code></pre>
  
  <p>At the moment I have managed to pull the middle section out using the following expression inside a variable:</p>
  
  <pre><code>$F{String}.split("/" ,5)[1].trim()
  </code></pre>
  
  <p>To be perfectly honest I am not sure how it works as I do not know what the 5 and 1 are for (which is probably what I need to know to get the other two sections)</p>
