Private fields, not really private?

[P0jahn]

Since we can access private fields(and probably methods as well, havent checked) with reflection, they are not really private.

http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Field.html#get(java.lang.Object)
http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Field.html#set(java.lang.Object,%20java.lang.Object)

and

field.setAccessible(true);

Is there a way to make a field 100% private?
