Comparison of Ways to Check Preconditions in Java[^]

Quote:

The use of preconditions, postconditions and invariants is extremely helpful to develop maintainable code. Unfortunately, we find preconditions quite seldom in real world applications. [...] Guava Preconditions and Apache Commons Validate class are the best choice and have almost the same functionality (just take what is more convenient in your technology stack)

Use Preconditions in your code - this is most of the time better than a lot of comments. but don't use asserts as preconditions
