Implicit Constructor

[Akash Roy]

Hi,
Suppose i define a class public class Test{} in a package abc. But do not define any constructor. So in this case an implicit default constructor Test() will be provided by Java. But then how can the class be instantiated from outside the package abc. Since the constuctor Test() will have a default scope. Thanking in Advance.

Regards,
Vallabh

A default constructor provided by the compiler has public access if the class itself is coderanch, or default access otherwise. So in this case, the default constructor will be coderanch.

However, if Test is in a package abc, then classes outside of that package will need to import abc in order for the Test class to be visible.

EDIT: Note clarification below.

the default constructor has public access

[shandilya popuru]

the default constructor has the same access modifier the enclosing class

Not quite true.
JLS 2e 8.8.7 states:

If the class is declared coderanch, then the default constructor is implicitly given the access modifier public (�6.6); if the class is declared protected, then the default constructor is implicitly given the access modifier protected (�6.6); if the class is declared private, then the default constructor is implicitly given the access modifier private (�6.6); otherwise, the default constructor has the default access implied by no access modifier.

Tony is correct, of course. (I was assuming a top level class.)
