Orientação a Objetos com Java from Coursera

Neste curso, assumimos que você já sabe desenvolver programas pequenos em Java, mas você talvez não se sinta ainda confortável em projetar programas mais complexos com método e organização.

O objetivo deste curso é fazer você compreender os princípios de orientação a objetos por meio da linguagem Java e saber como eficientemente aplicar esses princípios na prática quando projetando e desenvolvendo software de maneira ágil. Os conceitos discutidos e experimentados por você neste curso serão a base para você poder compreender os novos conceitos apresentados nos cursos seguintes desta especialização.

Os conceitos Java apresentados neste curso incluem o seguinte: revisão de conceitos básicos de orientação a objetos, tais como classes, objetos, métodos e atributos, variáveis de instância e de classe; responsabilidades, colaborações e cartões CRC; testes de unidade, uso de plataforma IDE como o Eclipse; herança, classes concretas e abstratas, interfaces, modificadores de acesso, encapsulamento, métodos de acesso; aprofundamento nos conceitos de polimorfismo, sobrecarga e sobreposição; associação de classes, agregação e composição; exceções, delegação e acoplamento abstrato. Em seguida, vocês serão apresentados aos principais princípios usados para organizar o desenvolvimento de programas orientados a objetos com qualidade, dentre os quais, os princípios "Tell, Don't Ask!" e "Law of Demeter". Sempre que conveniente, cada conceito será representado por meio de diagramas UML. Você será exposto a propriedades e anotações em Java.

Ao final deste curso, você terá amadurecido de tal modo suas habilidades de programação que você será capaz de implementar versões iniciais do componente de gamificação constante do Trabalho de Conclusão da Especialização, com base nas boas práticas exercitadas neste curso.
