Java regular expression with groups

问题

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

回答1:

I guess you can use replaceAll:

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

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

回答2:

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

回答3:

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

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