Boa noite,

supondo que eu faço o import de uma classe de uma package chamada x, cuja classe é Y.

faço:

import x.Y;

e quando quero utilizar um método da classe Y simplesmente escrevo o nome do metodo ou tenho que escrever x.metodo()?

Se for um método static:

Y.metodo();

Se for um método de uma instância tens que criar o objecto primeiro:

Y y = new Y();
y.metodo();

“There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.”
