title: simple maze game in java
body: <p>I am creating a simple maze game in java. The code reads a data file and assigns it to a <code>String array</code>. The player inputs what direction he or she would like to go in and each position contains a certain number of <code>points (0, 1, or 2)</code> that corresponds to the <code>obstacleNumber (0, 1, or 2)</code>. I want to keep track of the points as well as the number of times the player has moved but I cannot figure out where to call my methods to make sure that the counting is correct. I'm sorry if this is a really stupid question but I am new to java! </p>
  
  <p><em>The array is being filled correctly but I cannot count the moves and points.</em></p>

  </code></pre>
  
  <p>The data file has the size of the array (4 4) and an obstacleNumber and obstacle </p>
  
  <pre><code>    0 this obstacleNumber would award 0 points
      1 this obstacleNumber would award 1 point
      2 this obstacleNumber would award 2 points
  </code></pre>
  
  <p>16 times to fill the array.</p>
  
  <p>I would like the sample output to print the player location (which it does correctly), ask the user to input a direction (which it does correctly), print the text in the data file (again already done) and then print the number of moves already used and the amount of points the player has gained so far. </p>
  
  <p>How do you correctly calculate the number of times the user typed "<code>up, down, right, or left</code>" and how many points does the user have so far? Thank you in advance for your help I sincerely appreciate your time.</p>
