+#Adapter - Design Patterns#
+
+O padrão "Adapter" permite que classes que possuem interfaces "incompatíveis" consigam trabalhar juntas. Para isto,
+cria-se um "Adaptador" que utiliza dessas classes oferecendo uma nova interface que atenda a nova necessidade.
+
+Adapter é uma abstração intermediária que traduz ou mapeia um comportamento (classes, métodos ou funções) antigo
+do sistema para uma nova interface aceita pela nova arquitetura do sistema.
+
+Em outras palavras podemos dizer que o padrão Adapter converte uma classe em uma interface que outra classe espera.
