title: Trying to get input from JTextfield and use in another method
body: <p>Im having issues with trying to store values from a <code>JTextfield</code> located in method GuessGame() and put them into an array located in findMiddleNumber(). All i get when the program ends is the last input from the user which is the randomNumber.</p>
  
  <p>Could someone please have a look at my code and see where i'm gong wrong please</p>
