You will examine how objects of derived classes have independent copies of member variables, even from the derived class. Then move on to recognizing how the methods derived from work, and also how all built-in Java classes possess the methods derived from. Next, learn the concepts of polymorphism, its advantages and applications. You will then apply inheritance to model real-world entities. Begin with an introduction to inheritance, and how to identify its advantages and applications. In this course, you will explore the basics of inheritance and run-time polymorphism in Java, and how these concepts can be used to model Is-A relationships.
Finally, you will learn how to reassign a reference value in a method.
As you progress, other key areas include how to add method parameters to overload a constructor, how to pass an Object Reference, and pass a value. Next, you will learn how to use public and private access modifiers, study encapsulation with object-oriented design, and create class setter methods with value checking. Other topics include how to convert strings to their primitive numeric types, ciscover access control, and how to distinguish between the public interface and the internal workings of a class.
These include the following: how to create and access static members, how to employ constants to represent unchangeable values, how to change numeric variable types through promotion and casting, and convert data values. During this course, you will discover various static methods and variables and explore a number of topics.
