title: Java Changing State
body: <p><code>i</code> represents rows and <code>y</code> represents columns in a connect 4 game, I am trying to change the color of the circle depending on the column the user has selected but this code keeps giving an error type mismatch cannot convert state to string.</p>
  
  <pre><code>public enum State{
      RED, YELLOW, BLANK;
  }
  </code></pre>
