If you really want to use regex:
Pattern p = Pattern.compile(".*"(.*)".*");
Matcher m = p.matcher("your "string" here");
System.out.println(m.group(1));
Explanation:
.* - anything
" - quote (escaped)
(.*) - anything (captured)
" - another quote
.* - anything
However, it's a lot easier to not use regex:
"your "string" here".split(""")[1]
