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.

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.

Module 2 : Abstract Classes & Debugging
Did you know you can declare a method without defining it? It’s like giving a method a name, and even parameters and a return type, with no code in the body. These are called abstract methods. To define abstract methods, we’ll learn how to create abstract classes. With these new concepts and structures, we’ll continue to expand our Java knowledge and develop our programming skills. We’ll also learn how to better debug our programs by running them interactively using Eclipse’s Debugger. This will allow us to watch the source code and the variables, during execution.

Module 3 : File I/O & Exceptions
There are multiple ways of loading and storing data in Java. Information can be stored and manipulated in different kinds of data structures. But data can also be stored in external files and then loaded into Java. In this module, we'll see how Java can communicate with the outside world by opening, reading from, and writing to, external files. This means of communication known as I/O or input/output, is extremely powerful with an overwhelming number of options. Any given I/O is not particularly difficult, but the difficulty lies in finding your way through the maze of possibilities. This module will help guide you through some of the different ways you can interact with external files. In addition, it will demonstrate methods you can use to handle errors and exceptions that may arise in your Java programs. In particular, when you're dealing with files.

Module 4 : Collections, Maps, & Regular Expressions
In this module, we're going to look at some advanced techniques for storing and manipulating data in collections, which are structured groups of objects. Specifically, we'll learn how to leverage Java's collections framework, which is a unified architecture for representing and manipulating different kinds of collections. We already have experience working with one type of collection in particular, and that's the ArrayList. We'll also learn how to leverage maps, which are dictionaries that associate keys with values. This module will also provide an overview of some advanced techniques for parsing text. In particular, we'll learn how to use regular expressions or regex, which are special sequences of characters that describe patterns used for searching, editing, and manipulating text and data.

Sobre Programa de cursos integrados Introduction to Programming with Python and Java
This Specialization starts out by teaching basic concepts in Python and ramps up to more complex subjects such as object-oriented programming and data structures in Java. By the time learners complete this series of four courses, they will be able to write fully-functional programs in both Python and Java, two of the most well-known and frequently used programming languages in the world today.
