Assume you are writing a unit test and want to make sure the object returned by a method is correct.  We have two objects, expected (which is the object we want to get) and actual (the object the code actually returned). Which of the following is true? A. Unit tests should only check if the class variables are identical. B. We can use assertEquals(expected, actual) only if the equals method has been properly overridden, otherwise we must either check that all the getters return the same values, or that the toString returns the same value. C. We cannot compare objects directly in a unit test. D. Black box testing means we can't ever know if what is inside two objects are the same.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
