    It's very hard to understand what you are asking, but you should probably go and read up some basics about classes: [Java Tutorials: Declaring Member Variables](https://docs.oracle.com/javase/tutorial/java/javaOO/classvars.html) – OH GOD SPIDERS Mar 05 '18 at 11:32

  • This is a **field** in your class. Super basic stuff, written up in any good book or tutorial. Seriously: consider deleting this question. – GhostCat Mar 05 '18 at 11:35
  • Ghostcat, is there a lower limit on how basic SO questions are allowed to be ? – Erwin Smout Mar 05 '18 at 11:39

    @ErwinSmout That is a bit of grey area. If it is so basic that you encounter it doing 1 minute of research, consider it to be basic. And the other point is: this is a duplicated question. Unfortunately I voted for "close as unclear" before figuring that I should have closed as duplicated instead. – GhostCat Mar 05 '18 at 11:41

It just creates an object from the MesgBean class. The object remains NULL until you initialize it using constructor. This does not have any connection with being public or private.

It declares a member in the type that this declaration appears in.

The member's name is "bean".

The member's type is "MesgBean" (in the same package as the one of the type (/class) that this declaration appears in).

The member is not initialized.

And the "private" part means the member will only be visible to code within this type.
