Extending class Object 02

Question 1

• What is the difference of testing equality using the equals() method or the == operator, and where are they both appropriately used?

Answer 1

==: checks if both objects point to same memory location

Equals(): Evaluated to the comparison of values in the objects

They are both used in toString methods.

Question 2

• What is the default behaviour of the equals() method you inherit from class Object?

Answer 2

The default equals method compares memory addresses, which means that all objects are different from each other
