title: Converting java string to uppercase without using toUpperCase method
body: <p>What I have so far</p>
  
  <pre><code>public String toUpperCase(String str)
  {
      int strLength = str.length();
      String word = "";
      while (strLength &gt; 0)
      {
          char newStr = str.charAt(strLength);
          Character.toUpperCase(newStr);
          Character.toString(newStr);
          word += newStr;
          strLength--;
      }
      return word;
  }
  </code></pre>
  
  <p>I'm completely lost and my code is probably illogical. Some help would be appreciated</p>
