Inheritance and Data Structures in Java

Brandon Krakowsky

Brandon Krakowsky

This course provides a comprehensive look at Java inheritance, including access modifiers and overriding methods. Students are introduced to abstract classes, and will learn how to read and write to files, use regular expressions for parsing text, and how to leverage complex data structures like collections and maps.

Additionally, this course offers strategies for catching errors and debugging code, including an overview of Eclipse’s debugging tool.

Syllabus

Module 1 : Inheritance, Polymorphism Using Overriding, & Access Modifiers

We’ll start this module by talking about inheritance, a core concept in object-oriented programming. It’s the mechanism by which one class inherits the fields and methods of another class. Then we’ll learn about another aspect of polymorphism, overriding, which is creating a method in a subclass having the same signature as a method in a superclass. In particular, we’ll look at overriding the toString method for printing your objects and the equals method for comparing your objects, especially as it relates to unit testing. Finally, how you can restrict scope in a program by using modifiers to control access to variables, methods, and classes.
