abstract property cannot be accessed in the constructor

The subclass that defines the concrete property can create access methods and specify initial values. Abstract properties cannot define access methods and cannot specify initial values. Since x is an instance variable, it cannot be directly used inside a main method. Concrete subclasses must use the same values for the SetAccess and GetAccess attributes as those attributes used in the abstract superclass. The abstract class can also include an abstract property, as shown below. You can write the code to access x without creating an object such as foo in this code. The class which implements an abstract class must call super() in the constructor.

Since it does not belong to the property class, it is not allowed to be static. But a constructor is called when a new operator is used to create an instance. Methods aren't inlined for purposes of CFA, and shouldn't be since they're virtual - the design contract of this class may well be 'Initialize this.property then call super. Since x is defined in the class Foo, it can be accessed by any method inside the class without using an object. In Java, static methods and variables apply to the classes.Abstract property cannot be accessed in the constructor … Abstract property uploadType in class BaseUploadComponent cannot be accessed in the constructor. it cannot be accessed from outside of its containing class.
