    Default [java] access to member in composition

    Qt Code:
    1. //a.class
    2. public class A {
    3. private static enum Day { Sun, Mon, Tue }
    4. private B b;
    5. public A (B cb) { b = cb; }
    6. friend B; //exists??
    7. }
    8. //b.class
    9. public class B {
    10. public B () { }
    11. private int DoSomething () {
    12. // here I have to acces to enum Day like switch (Day) ; but from here
    13. }
    14. }
    To copy to clipboard, switch view to plain text mode 
    Does it exists a keyword like "friend" to do this? Or Anyone can suggest me anything better!?

    Furthermore: is it possibile something like C ? (= 0 I mean)
    Qt Code:
    1. private static enum Day { Sun=0, Mon=1, Tue=2 }
    To copy to clipboard, switch view to plain text mode 
    thanks

    Java doesn't have the "friend" concept. In Java you have the option of nested classes or private, file scope classes.

    You can use either of them, from what I see you're trying to do.

    Here's a nice thread that goes into the more "philosophical" aspects of this issue: http://forum.java.sun.com/thread.jsp...sageID=2358324
