Check for a Substring after a particular occurrence of string which is separated by dots

I have a string with dots. I want to get a particular substring after occurrence of word

entity

that is for example

String givenStr = "com.web.rit.entity.TestName.create";
output - TestName

String givenStr = "com.web.rit.entity.TestName2.update";
output - TestName2

So as explained above I have to extract substring after the string entity from the given string. Can anyone please help? (I am using java to do it).

Answer

You can do something like this :

String givenStr = "com.web.rit.entity.TestName.create"; // begin str
String wording = "entity"; // looking for begin
String[] splitted = givenStr.split("\."); // get all args
for(int i = 0; i < splitted.length; i++) {
    if(splitted[i].equalsIgnoreCase(wording)) { // checking if it's what is required
        System.out.println("Output: " + splitted[i + 1]); // should not be the last item, else you will get error. You can add if arg before to fix it
        return;
   }
}
