Regex in java, group matching

Question

Hello how does java and regex group work. For ex. I want to match any text 'something' , the way I'd match this is .+\\s+'(.+)'{1} , how can I replace any text 'something' with something?

Meaning replace matched string with 1st matched group.

If you just want to remove the single quotes, the following will work.

yourString.replaceAll("'([^']+)'", "$1");

That will search for 2 quotes with text in between. And replace it with only the text.

System.out.println("any text 'something'".replaceAll("'([^']+)'", "$1"));

Prints any text something
