title: Making a line of code difficult to read
body: <p>Im writing a way of checking if a customers serial number matches my hard coded number. Is there a way of making this as hard to read as possible in case an undesirable gets their hands on the code? </p>
  
  <p>I am working in java.</p>
  
  <p>For instance (pseudo code)</p>
  
  <p>if (x != y) jump out of code and return error </p>
  
  <p>Cheers , apologies if this is a bit of an odd one </p>
