title: How can I use string builders to shorten this string?
body: <p>I have this which is used to enable GC logging:</p>
  
  <pre><code>updateJVMArguments("-Xloggc:gc_" + myapp.getFileName() + "-" + getDateTime() +".log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=2M");
  </code></pre>
  
  <p>As you can see it is pretty long, is there anyway to use StringBuilders to make it a bit shorter and even use variables to pass in the <code>2M</code> and <code>5</code>?</p>
