public keyword

[emil gasanov]

Hi everyone, just a little noobish question: is there a difference between

public void x() {}

and

void x() {}

And if there is, what it it? Is omitting the "public" keyword makes any difference to the availability of the method?

The second one cannot be accessed from outside the package.

Is it the same case for classes?

Yes. Classes can be declared without any access modifiers, the "default" access modifier means that this class will be visible only within current the package.

Yes it is. The only difference is with interfaces. If you omit access modifier in method signatures of interface, they are still all public.

The topic Controlling Access to Members of a Class in Oracle's Java Tutorials explains exactly what the difference is between public, protected, private and no access modifier.
