which assert statements are used appropriately?

Because it is validating an argument of a public method

because x is the parameter of a public method and it is inappropriate to check them.....because after all it is public method which can be accessed by any client....and the client doesnt know if there were supposed by a check on the argument passed to the method...

----------------------------------------------
Its a rule that assertions should not be use to check the arguments passed to a public method

To know the reasons you can check SCJP5-Paul Sanghera CHP 7(pg 190).

I would like to know how assertions work with private methods ?
