static void sound()
{System.out.println("apple!");}
}
class Myclass{

Answer 1

Yes you have given a correct explanation in your code for static methods.

Answer 2

Static members are class level and can be accessed directly without any instance.
While with non-static members you need an instance (Object) of that class to access them!

So static methods are called like:
ClassName.method();
And non-static methods:
obj.method();

Answer 3

@André Martins so i have explain it correctly right?
