Let's say we have the series of strings to parse: ${32.82}, ${we5}, ${x4Rvc}, ${123}. It is clear that we are looking for: ${x*}. But the proper regular expression is actually much more complicated:

Pattern myPattern = Pattern.compile("\\{\\$(\\w*)\\}");

The complexity arrises from the escaping of characters. Some characters have ordinary meaning to you, but have special meaning in the context of regular expression engine. There are many special characters, too many to recall.

There is an easier way!

Several products like Lapis were created to overcame this problem. incomplete
