Reports calls to the regular expression methods (such as matches() or split()) of java.lang.String using constant arguments.

Such calls may be profitably replaced with a private static final Pattern field so that the regular expression does not have to be compiled each time it is used.

Example:


  text.replaceAll("abc", replacement);

After the quick-fix is applied:


  private static final Pattern ABC = Pattern.compile("abc", Pattern.LITERAL);
  ABC.matcher(text).replaceAll(Matcher.quoteReplacement(replacement));
