Date: 2012may11 Language: Java Q. Java: Why is String.split() not giving me empty strings?

String subject = ":"; String []a = subject.split(":");

Gives me an a.length == 0 but I expect 2. A. Regular split (helpfully) deletes trailing empty strings. So use the other form of split:

String subject = ":"; String []a = subject.split(":", -1);
