This course explores member functions and their invocation in Java. learners begin by studying object references and learning the subtleties and nuances of how these references sometimes lead to unexpected results in a program. Learn to use a copy constructor to break references that existed from rectangle objects to the point objects and how they become self-sufficient. Next, you will see that the classes you created often have multiple overloaded methods, which can lead to code duplication. You will learn how to correctly chain the implementations of overloaded constructors and other overload methods. You will also begin to understand the reference variable, 'this' keyword, to avoid naming conflicts in constructor chaining. You will see how to create variables or methods that ought to be one per class, rather than one per instance using the static keyword. Finally, you will become familiar with the different rules that govern how static members and methods are accessed, and how some forms of access that are allowed by the Java compiler are not considered a best practice.
