Constructors are having a special signature, different from ordinary member functions ?

Hi !



Take a look at the following code:

public class CDummy
{
public static void main(String args[])
{
System.out.println("CDummy.");

CDummy dmy = new CDummy();
}

CDummy() {System.out.println("CDummy()");}

void CDummy() {System.out.println("void CDummy()");}
}


The constructor "CDummy()" and the member function "void CDummy()"
differ only by the return type. Normally, this is disallowed but since
constructors can only appear after a 'new' operator there is no
ambiguity, so this is allowed !!!

Well.. no question here. I hope I didn't messed up the explanation)

Actually, the reason it's allowed is because there's no conflict:
Constructors are turned into methods called "<init>" by the compiler,
so there is no collision with "normal" methods of the same name.
