  /**
   * A JSONArray is an ordered sequence of values. Its external text form is a
   * string wrapped in square brackets with commas separating the values. The
   * internal form is an object having <code>get</code> and <code>opt</code>
   * methods for accessing the values by index, and <code>put</code> methods for
   * adding or replacing values. The values can be any of these types:
   * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
   * <code>Number</code>, <code>String</code>, or the
   * <code>JSONObject.NULL object</code>.
   * <p>
   * The constructor can convert a JSON text into a Java object. The
   * <code>toString</code> method converts to JSON text.
   * <p>
   * A <code>get</code> method returns a value if one can be found, and throws an
   * exception if one cannot be found. An <code>opt</code> method returns a
   * default value instead of throwing an exception, and so is useful for
   * obtaining optional values.
   * <p>
   * The generic <code>get()</code> and <code>opt()</code> methods return an
   * object which you can cast or query for type. There are also typed
   * <code>get</code> and <code>opt</code> methods that do type checking and type
   * coersion for you.
   * <p>
   * The texts produced by the <code>toString</code> methods strictly conform to
   * JSON syntax rules. The constructors are more forgiving in the texts they will
   * accept:
   * <ul>
   * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
   *     before the closing bracket.</li>
   * <li>The <code>null</code> value will be inserted when there
   *     is <code>,</code>&nbsp;<small>(comma)</small> elision.</li>
   * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
   *     quote)</small>.</li>
   * <li>Strings do not need to be quoted at all if they do not begin with a quote
   *     or single quote, and if they do not contain leading or trailing spaces,
   *     and if they do not contain any of these characters:
   *     <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers
   *     and if they are not the reserved words <code>true</code>,
   *     <code>false</code>, or <code>null</code>.</li>
   * <li>Values can be separated by <code>;</code> <small>(semicolon)</small> as
   *     well as by <code>,</code> <small>(comma)</small>.</li>
   * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
   *     <code>0x-</code> <small>(hex)</small> prefix.</li>
   * <li>Comments written in the slashshlash, slashstar, and hash conventions
   *     will be ignored.</li>
   * </ul>
