title: How to detect if a string contains a specific Word
body: <p>I have this code :</p>
  
  <pre><code>if (currentLocation.distanceTo(myModel.getNearest()) &lt; 900) {
  
          if (said != true) {
  
              String seriousWarning = (myModel.getNearest().getProvider());
              tts.speak(seriousWarning, TextToSpeech.QUEUE_ADD, null);
              said = true;
  
  
                   warningTxt.setTextColor(Color.RED);
          }
  </code></pre>
  
  <p>I would like to check if there a certain word in the seriousWarning string, knowing that (myModel.getNearest().getProvider()) is the title of the nearest GPS point to the device.</p>
  
  <p>Any help would be much appreciated!</p>
