Students will learn about Classes & Objects, Inheritance and Polymorphism, Nested Classes and Creating Interfaces in the Java Programming Language
This unit introduces the concept of classes and objects, and discusses the procedure for declaring classes and creating objects.
You will learn to declare instance variables, methods, and local variables by using permitted modifiers such as public, protected, private, and package.
You will also learn to invoke overloaded constructors and chain constructors.
You will learn features of the object-oriented programming (OOP) approach, which are inheritance and polymorphism. The unit also covers the procedures for reusing code and extending the use of existing classes by inheritance. In addition, you will learn about the features of subclasses and relationships between classes.
You will also learn about the procedure for and the effect of invoking overloaded and overridden methods.
You will learn about the procedures for upcasting, downcasting, and identifying objects. This unit gives explanation of the keywords super and this.
You will also learn to use the object reference super to access variables and invoke the methods of the superclass and the object reference this to refer to the current object. Additionally, this unit details the procedures for declaring and using the static and final variables, methods, and final classes. The unit explains the implementation of abstract classes and dynamic method binding. This unit explains interfaces and packages.
You will learn to implement interfaces and conceive a form of multiple inheritance.
You will also learn how to create packages and import the packages into your Java source file to incorporate the already existing classes in your program.
