How can I split string for 3 character? (I don’t want to do loop for this, maybe some regular expression will be help)
I give example:
String str = "111222333444";
String[] result = str.split("help?"); // get "111", "222", "333"
Using guava-library
Readable than using regex. You can then use
Ints.tryParse(...)to get Integer version if you want.
