Debug.assertNotNull介绍

[英]If the given object is null, and the debugging functionality is enabled, this method throws an AssertionFailure in order to signal that an internal program post- or pre-condition failed.

Use this method whenever a valid state must be ensured within your sourcecode in order to safely continue the program.

For example, the method can be used to ensure valid arguments passed to private and protected methods.
