Question

The regular expression I am trying to use is

 String re2="((?:(?:[1]{1}\\d{1}\\d{1}\\d{1})|(?:[2]{1}\\d{3}))[-:\\/.](?:[0]?[1-9]|[1][012])[-:\\/.](?:(?:[0-2]?\\d{1})|(?:[3][01]{1})))(?![\\d])";    // YYYYMMDD 1

But when I try to replace all occurrences,

string.replaceAll(re2,getDate(dayForward,dateFormat));

doesn’t work. And,

matcher.appendReplacement(stringBuffer, getDate(dayForward,dateFormat));

only replaces the first occurrence.

Is there any way I can replace all the occurrences?

Answer 1

You have to put the result in an other variable:

String replaced = string.replaceAll(re2,getDate(dayForward,dateFormat));

Otherwise, it means your regex is not right.
