Modeling Entities in Java: Static Members, Arguments, & Method Overriding

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. The best way to avoid mysterious bugs while running your Java code is to be adept at working with static members, argument passing, and object base class methods​. Use this course to master these subtleties: the difference between static and instance variables and methods, the hashCode contract, and how pass-by-value and pass-by-reference semantics play out with argument passing in Java. By the end of this course, you'll be able to model state in classes using both static and instance variables, write methods to avoid unexpected changes in input arguments, and adhere to the hashCode contract so that objects function as expected when placed in common Java containers.
