java equivalent of assert( 0 && "description")

Question

What is the Java equivalent this?

assert(0 && "description");

I've tried

assert(false && "description");

But Java types are too strict for that. Any tips on the idiomatic way to add a description to an assert statement?

What is that supposed to do? `"description"` is not a boolean value. What case are you trying to "assert"? — , Jul 23 '20 at 10:20
in c++ one would often write a description of what was violated in the assert. For instance, `assert(0 && "one should not get here ...");` — OrenIshShalom, Jul 23 '20 at 10:21
in c++ when the assertion is hit, the description will be printed to screen, helping in debug by describing what bad thing just happened — OrenIshShalom, Jul 23 '20 at 10:22
Hopefully you don't think Java's assert mechanism is used for the same things as in C++. It's definitely not for regular debugging which seems to be your goal. — Kayaman, Jul 23 '20 at 10:39
Are you maybe looking for e.g. `Objects.requireNonNull()` or something similar where you can provide a message? — , Jul 23 '20 at 10:47

You can add a description to an assertion using:

assert false : "description";

This is described as

assert Expression1 : Expression2 ;
