package-private

I am trying to get an instance of a non-visible class, AKA package private class, using reflection. I was wondering if there was a way to switch the modifiers to make it public and then access it using Class.forName . When I try that now it stops me saying I can't do it. Unfortunately there is no setAccesible method of the Class class. Pshemo nested class - class defined within other class (includes static and non-static classes) inner class - non-static nested class (instance of inner class need instance of outer class to exist) non-nested (top level) classes Based on your question we know

Since an enum constructor can only be invoked by its constants, why is it then allowed to be package-private? ColinD The constructor actually isn't package-private... it's implicitly private the way interface methods are implicitly public even if you don't add the keyword. The relevant section of the JLS ( §8.8.3 ) states: If no access modifier is specified for the constructor of a normal class, the constructor has default access. If no access modifier is specified for the constructor of an enum type, the constructor is private . It is a compile-time error if the constructor of an enum type (

I am learning Java recently, and I came across the notion of package-private classes, which is the default if we don't specify anything. But then I realized: I seldom see the use of package-private class. Is there a reason for this, e.g., it has serious drawbacks, it is redundant, or simply I am not reading enough? Are there strong arguments for/against its usage? If it is really not useful in most cases, why would it be the default? In what situation should we use package-private in the real world? I.e., when would it become irreplaceable? In other words, what are the major pros and cons of
