title: Print a range of characters as a list
body: <p>So my method is supposed to take to character parameters as the first and last characters in a range and print every letter and its numerical encoding in the range. For example e and j as parameters would print out e f g h i j (except with the nnumerical encoding) 
  The code I used doesnt compile. What am I doing wrong</p>
  
  <pre><code>public void listCharacterCodes(char a, char b){
      int j = (int) b;
      for(int i =(int) a, i&lt;j,i++){
          println("'" + a + "': " + i);
      }
  }
  </code></pre>
