Search for a substring between special character in a string

Question

I have a string like (&(objectclass=${abc})(uid=${xyz})) How can I search ${abc} and ${xyz} and replace with another strings. There can be any number of occurence of such substrings i.e.${abc} in main string. I was thinking of string.indexOf( but that could be messy. Any best approach? ${abc} will be replaced by another string abc. I will get them from some other parameters.

Answer 1

You need to escape special characters ($ , { , } ). Try this: str.replaceAll("\\$\\{abc\\}","abc"); This can be weird but can help you out: str = str.substring(str.indexOf("${")+2, str.indexOf("}")) This will work for all (any number of) strings between ${ and }.
