Extract Text Between Parenthesis To extract the text between any characters, use a formula with the MID and FIND functions. The FIND Function locates the parenthesis and the MID Function returns the characters in between them.
The simplest way to extract the string between two parentheses is to use slicing and string. find() . First, find the indices of the first occurrences of the opening and closing parentheses. Second, use them as slice indices to get the substring between those indices like so: s[s.
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(")")); 
List<String> matchList = new ArrayList<String>(); 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); } OUTPUT
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.
