Programming With Assertions An assertion is a statement in the Java TM programming language that enables you to test your assumptions about your program. For example, if you write a method that calculates the speed of a particle, you might assert that the …
Programming with assertions (a.k.a. assert statements) is a great idea . because they provide run-time checks of assumptions that you would have otherwise put in code comments. the run-time execution environment knows nothing about comments; comments often get …
Programming with Assertions. April 21, 2004 Cletus the Codeslinger . I am amazed to see how much programmers take for granted. For example, I have worked on many programs in which the author had assumed that an RPG CHAIN operation (a random read) would always find the sought-for record.

In the previous guide, Programming with Assertions in Java Part 2, I discussed some best practices for using assertions and where not to use them. In this guide, I’m going to talk about some misconceptions about assertions and wrap up the series.
Encourages programming with assertions by providing tools to compile them away. – unassert-js/unassert

I wonder if a lot of people program in java with assertions. I think this can be very useful on large projets without enough written contracts or outdated contracts. Particulary when you use webser
Btw, do you refer to assert in java?
I personally find assertions especially useful for invariants. Take into account that assertion checking is turned off by default in java. You have to add the -ea flag to enable assertion checking.Beste Antwort · 5About the minor usage of asserts I think that was a bad decision to make assertions disabled by default.
About extending Error I suppose it extends Error because Errors are exceptions that are not expected to be catched. And that way when in your code you have catch(Exception) the assertion isn’t cached.4In my opinion errors in Java should be trated as an Exception. Therefore I would enable assertions in development and in private methods to check that my code is running fine and don’t passing invalid values to private methods.
Since those checks should be made in public methods, I wouldn’t not check again in private methods.1
