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.

Perguntas Frequentes – FAQ

Quando terei acesso às palestras e às tarefas?
O acesso a palestras e tarefas depende do tipo de inscrição. Se você participar de um curso como ouvinte, você poderá ver quase todo o conteúdo do curso gratuitamente. Para acessar tarefas valendo nota e obter um Certificado, você precisará adquirir a experiência do Certificado, durante ou após a participação como ouvinte. Se você não vir a opção de participar como ouvinte:
o curso pode não oferecer essa opção. Você pode experimentar um teste gratuito ou solicitar o auxílio financeiro.
Em vez disso, o curso pode oferecer 'Curso completo, sem Certificado'. Com esta opção, é possível ver todo o conteúdo do curso, enviar as avaliações necessárias e obter uma nota final. Isso também significa que você não poderá comprar uma experiência de Certificado.
O que recebo ao me inscrever nesta Especialização?
Quando você se inscreve no curso, tem acesso a todos os cursos na Especialização e pode obter um certificado quando concluir o trabalho. Seu Certificado eletrônico será adicionado à sua página de Participações e você poderá imprimi-lo ou adicioná-lo ao seu perfil no LinkedIn. Se quiser apenas ler e assistir o conteúdo do curso, você poderá frequentá-lo como ouvinte sem custo.
Existe algum auxílio financeiro disponível?
Sim. Em programas de aprendizado selecionados, você pode solicitar auxílio financeiro ou uma bolsa de estudos caso não consiga pagar a taxa de inscrição. Se o auxílio financeiro ou bolsa de estudos estiver disponível para a seleção do seu programa de aprendizado, você encontrará um link para se inscrever na página de descrição.
How much math do I need to know to take this course?
The only math that learners will need for this Specialization is arithmetic and basic concepts in logic.
This course was fun. How can I learn more?
If you enjoyed this course, we recommend Courses 1, 2 and 3 in the series!
If you would like to learn the fundamentals of computer science beyond the basics of programming, consider applying to the Master of Computer and Information and Technology (MCIT) at the University of Pennsylvania, an Ivy League computer science master’s program for people without a computer science background. For an on-campus experience, explore here. If you prefer an online setting, apply to MCIT Online. In fact, the lectures in this series are also used in the online degree program! The Specialization certificate will be viewed favorably by the admissions committee, so be sure to mention it when you apply.
