Assertions allows us to verify the correctness of an invariant in code. They should never be triggered in production codeThey can be activated at run-time by way of the -ea option on the java command but are not turned on by default. An example: public Foo acquireFoo(int id) { Foo result = null; if (id > 50) { result = fooService.read(id); } else { result = new Foo(id); } assert result != null; return result; } Complete discussion: http://stackoverflow.com/questions/2758224/assertion-in-java
