    IDEA is probably becoming sentient and adding its own menus.

    Why is 
    b
    resolved in this example, but isn’t not in the next one:

    Because the reference type of a in the first example is..well... the object type 'a' In the second example the reference type of a is A

    Java equivalent to the second example is 
    A a = new A() {private final int b = 1; /*with getter*/};

    Ah, I see what you mean. So then what’s a point of defining an object the way I do in the second example and not being able to reference it’s properties and methods?

    To be able to pass it to functions. I.e create a subclass with object on the fly. As in Java's anonymous classes

    when no new API is needed in the object

    To @Kirill Zhukov’s point: it’s indeed a bit confusing that 
    :object A()
    is very different from 
    : A()

    But if I do want to change API in some cases 🤔 Here is an example:
  • k

    Now having this I want to add another function 
    foo3()
    to 
    a
    object. My first intuition was:
  • k

    And since 
    foo3()
    isn’t resolved, I can do it this way, but then I have to import 
    Foo
    again...

    Then you should use the other syntax for declaring a

    What is your end goal with this?

    Being able to do this

    I mean, I cannot explain my actual problem, it’s all abstract of course.

    Kirill Zhukov

    11/30/2016, 9:02 PM
    This works though:

    And don’t need to import 
    Foo
    object here inside of the 
    Foo
    function
  • o

    okkero

    11/30/2016, 9:04 PM
    How about declaring MyA outside Foo?
  • k

    Kirill Zhukov

    11/30/2016, 9:05 PM
    But then it’s accessible from anywhere
  • k

    Kirill Zhukov

    11/30/2016, 9:05 PM
    Let me see, if I can make it internal though
  • o

    okkero

    11/30/2016, 9:06 PM
    Isn't it already accessible from anywhere??
  • o

    okkero

    11/30/2016, 9:06 PM
    I can just do Foo.MyA
  • k

    Kirill Zhukov

    11/30/2016, 9:06 PM
    Only through 
    Foo
    object, right?
