Answer 1

List matchList = new ArrayList();
Pattern regex = Pattern.compile("\\((.*?)\\)");
Matcher regexMatcher = regex.matcher("Hello This is (Java) Not (.NET)");

while (regexMatcher.find()) {//Finds Matching Pattern in String
   matchList.add(regexMatcher.group(1));//Fetching Group from String
}

for(String str:matchList) {
   System.out.println(str);
}

Java
.NET

What does \\((.+?)\\) mean?

This regular Expression pattern will start from \\( which will match ( as it is reserved in regExp so we need escape this character,same thing for \\) and (.*?) will match any character zero or more time anything moreover in () considered as Group which we are finding.
