Duvida => Se uma classe abstrata faz tudo que uma interface faz e um pouco mais, qual a vantagem ou necessidade de se utilizar uma interface em Java?

HappyHippyHippo Posted March 30, 2015 at 03:18 PM Report Share #580496 Posted March 30, 2015 at 03:18 PM porque uma classe abstracta não faz tudo que uma interface faz IRC : sim, é algo que ainda existe >> #p@p Portugol Plus Link to comment Share on other sites More sharing options...

HappyHippyHippo Posted March 30, 2015 at 03:35 PM Report Share #580498 Posted March 30, 2015 at 03:35 PM não podes ter uma classe derivar de várias classes abstractas, mas podes forçar uma classe implementar multiplas interfaces IRC : sim, é algo que ainda existe >> #p@p Portugol Plus Link to comment Share on other sites More sharing options...
