Appropriate use of Assertions

• AssertionError is a sub class of Throwable, so it can be caught. But sun not doesnot allow access to the object that generated it. We only get a String message.
• We should not use Assertions to validate arguments of a public method.
• We can use Assertions to validate arguments of a private method.
• We should not use Assertions to validate command line arguments.
• We should use Assertions which doesnot leave the state of the program in the same state.
