“The constructor is not visible” error

Question

I have two classes :

First, with one constructor :

public class First {

    First (ObjectA myObjectA) {
        //do stuff
    }
}

Answer 1

No access modifier for your constructor makes it package private. Assuming that First and Second are in the same package, you can call Second's constructors from first. Another class from another package, however, cannot access any of the constructors.
