Dynamic regular expression could be replaced by compiled 'Pattern'
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));
