Dear developers, I'm a graduate student doing software engineering research. Recently, I came across some interesting facts about Java assert statements and have a few questions to ask.
Although the assert keyword has been around for a long time and is handy for invariant checks, it does not seem to be widely used. For example, in the famous j.u.c packages, nearly all assert statements are commented out [1]. My questions are, should assert be heavily used in Java programs, especially in production code? And should we enable them in the production code? By the way, I have read a useful article about using assertions in Java [2], but it does not provide clear answers to my questions above. Thank you in advance!
