Java regular expression with groups

Question

I would like to replace all occurences of strings like:

"{something1}
"{someother2}
"{thing3}

but how to deal with group that contains string, not chars?

-- edit:

e.g. given String:

sometext "{something1}hello

I would like to have

sometext hello

or better, but its only replaceAll parameter

sometext "hello

i know how to use patterns like this: String pattern="[abc]" - this group contains chars. But I would like to make group of strings, not chars — Mateusz Chromiński, Aug 25 '11 at 10:37
I don't quite understand what you want to achive by this. What kind of Strings do you want to match? — , Aug 25 '11 at 10:38

I guess you can use replaceAll:

String b = a.replaceAll("\\{.*?\\}", "sometext ");

This will replace all characters surrounded by curly braces with the replacement string.

JK.

thank you for advice. I have completely forgot that String are immutable. – Mateusz Chromiński Aug 25 '11 at 10:49

Just build a regular expression using the | operator inside a group.

nor this: String pattern = "\"(\\{String\\}|\\{Long\\}|\\{Boolean\\}|\\{Number\\})"; nor this: String pattern = "\"({String}|{Long}|{Boolean}|{Number})"; have worked – Mateusz Chromiński Aug 25 '11 at 10:44

You could use the or '|' operator to match full strings -

subject.replace(/something1|someother2|thing3/g, ",");
