How to get value inside many regex keys?

Question

I am trying to get the values that are in braces as below:

{{{{{{{{{{{{{{{{{{value1 here!}}}}}}}}}}}{value2 here!}}}}}}}}}{value3 here!}}}}}}

I would like you to be selected as a group:

{value1 here!} {value2 here!} {value3 here!}

I'm doing the expression on the site Regex101 and applying it to my Java project.

Pattern p = Pattern.compile("\\\\{.*\\\\}");
Matcher m = p.matcher("{{{{{{{{{{{{{{{{{{value1 here!}}}}}}}}}}}{value2 here!}}}}}}}}}{value3 here!}}}}}}");
if (m.find()){
    String value1 = m.group(1);
    String value2 = m.group(2);
    String value3 = m.group(3);
}

How can I solve this problem?

`m.group(3)` suggests that you confuse *match* with *group*. Also your `.*}` will match everything it can, until last `}`.Maybe use `[^}]*}` instead. — Pshemo, Jan 04 '20 at 18:25
My question has nothing to do with the above association. The one that is associated with mine addresses another path ¯\(°_o)/¯ — sYsTeM, Jan 04 '20 at 22:54

You just need your glob match to match on non-brace characters:

\{[^{}]*\}

Regex101

This is accomplished by using the construct [^...] for negated character classes which matches all characters except the ones specified within the [^ and ] delimiters
