title: Array replaceAll() error
body: <p>I was wondering what's wrong with my regular expressions.I was trying to remove certain characters in a string with this code   </p>
  
  <pre><code>array[i] = array[i].replaceAll("[.,;:?!\"')\\(]","");
  </code></pre>
  
  <p>Everything works except for the \ character, it wasn't removed from string. Also I tried this code</p>
  
  <pre><code>array[i] = array[i].replaceAll("[.,;:?!\"')(\\]","");
  </code></pre>
  
  <p>and it gave me an error.</p>
  
  <p>What am I doing wrong?</p>
