5.13.1.Assertions give you a way to test your assumptions during development and debugging.

Assertions are typically enabled during testing but disabled during deployment.



Assertions are disabled at runtime by default. 

To enable them, use a command-line flag -ea or -enableassertions.



Selectively disable assertions by using the -da or -disableassertions flag.



You can enable and disable assertions on a class-by-class basis, using the following syntax:



java -ea -da:MyClass TestClass
