Pattern to extract text between parenthesis

How to extract string from "(" and ")" using pattern matching or anything. For example if the text is

“Hello (Java)”

Then how to get only "Java"?

Answer

Try this:

String x = "Hello (Java)";
Matcher m = Pattern.compile("\((.*?)\)").matcher(x);
while (m.find()) {
    System.out.println(m.group(1));
}

or

String str = "Hello (Java)";
String answer = str.substring(str.indexOf("(")+1, str.indexOf(")"));
