Desenvolvimento Ágil com Padrões de Projeto from Coursera

Neste curso, assumimos que você já sabe projetar e desenvolver programas mais complexos em Java, graças às boas práticas e princípios exercitados nos cursos anteriores; mas você talvez não se sinta ainda confortável em lidar com cenários mais complexos, onde é difícil desenvolver software com código de qualidade com flexibilidade suficiente para facilitar a implementação de mudanças repentinas de requisitos.

O objetivo deste curso é oferecer a você um aprofundamento em técnicas de programação orientadas a objetos pelo uso de padrões de projeto no contexto de desenvolvimento ágil.

Os seguintes conceitos são apresentados neste curso:

• Revisão de conceitos de orientação a objetos: abstração de dados, encapsulamento, herança e polimorfismo

• Reúso por meio de herança: padrões Null Object, Template Method e Factory Method

• Delegando comportamento com composição: padrões Strategy, Bridge, State e Observer

• Composição recursiva: padrões Composite e Chain of Responsibility

• Envolvendo objetos: padrões Proxy, Decorator e Adapter

• Estratégias para criar objetos: padrões Static Fabric Methods, Singleton e Builder

• Modularidade: padrão Dependency Injection

Ao final deste curso, você terá amadurecido de tal modo suas habilidades de programação que será capaz de implementar partes da aplicação Web final com o componente de gamificação enriquecido constantes do Trabalho de Conclusão da Especialização, aplicando onde apropriado alguns dos padrões apresentados neste curso durante a refatoração na prática TDD.

What's inside

Syllabus

Semana 1

Olá, bem-vindo ao Curso 5 – Desenvolvimento Ágil com Padrões de Projeto! Estamos contentes que você esteja aqui para se exercitar com padrões de projeto. Neste módulo introdutório, você será apresentado inicialmente a uma revisão rápida de conceitos de orientação a objetos pertinentes a padrões de projeto; depois, a uma introdução a padrões de projeto, onde você aprenderá a usar o padrão Strategy. Ao final deste módulo você também terá aprendido uma forma alternativa a construtores para instanciar objetos, na forma do padrão Static Factory Methods.

Semana 2

Olá, bem-vindo ao Curso 5 – Desenvolvimento Ágil com Padrões de Projeto! Neste módulo você aprenderá a identificar quatro padrões em que se utiliza a herança; depois, três padrões em que se utiliza a composição.

Semana 3

Olá, bem-vindo ao Curso 5 – Desenvolvimento Ágil com Padrões de Projeto! Neste módulo você aprofundará seus conhecimentos sobre composição recursiva, bem como com os padrões Composite e Chain of Responsibility, nos quais se emprega a composição recursiva. Você será exposto aos padrões Proxy, Decorator e Adapter, em cujas estruturas se faz uso do encapsulamento. Ao final, você aprenderá como criar classes em que se pode instanciar apenas um único objeto, na forma do padrão Singleton.

Semana 4

Olá, bem-vindo ao Curso 5 – Desenvolvimento Ágil com Padrões de Projeto! Ao final deste módulo, você terá aprendido a criar objetos por meio dos padrões Abstract Factory e Builder. Você terá aprendido também uma forma de modularizar seu código com base no padrão de projeto Dependency Injection. Ao final, você irá exercitar parte do conhecimento aprendido neste curso ao desenvolver uma pequena aplicação com gamificação!
