title: Taking char and int inputs
body: <p>I am currently working on a Knight's tour implementation in Java. I am trying to take the user input in the form (file)(rank) on my board.</p>
  
  <p>File would be a char (a, b, c or d) and rank an int (1, 2 or 3).</p>
  
  <p>I know how to get the input of these individually but how would I combine the input of the two, so that for example 'd2' is valid.</p>
  
  <p>I am a beginner to java so any help would be much appreciated.</p>
