No, it can't. A static method can't return an object that only exists if the
'outer'
object exists.
class A {
private B b;
public static B get () {
return b;
}
}
The method 'get' can be called without the existance of an actual A object,
by simply
calling "A.get ();". However, the private B object exists only if there is
an A object. How
can B be returned in "A.get ();" when A does not exist?
The only way this works is if B is static too. So instead of 'private B b'
it should be
'private static B b'.
Btw, I just tested it 'cause I was about to implement a Singleton in the
project I'm
working on.
