In Java, the @FunctionalInterface annotation is used to indicate that an interface is a functional interface. A functional interface is an interface that has only one abstract method. In other words, it is an interface that can be used as the target type of a lambda expression. Example: @F...
方法名:makeFunctionalInterfaceClass Types.makeFunctionalInterfaceClass介绍 [英]Create a symbol for a class that implements a given functional interface and overrides its functional descriptor. This routine is used for two main purposes: (i) checking well-formedness of a functional interface; (ii) per...
It is very simple to declare an int in Java. int x = 424_242; int y; By default, the value of an unassigned int will be 0. It is also possible to define an int in a method. But then, you must assign a value to the variable before you can use it. You can also easily per...

Firstly, intersections will be allowed to appear as types of fields, types of formal parameters and return values of methods, therefore they will be significantly used as target types for \\(\\lambda \\) -expressions anywhere. Secondly, the notion of functional interface will be extended to ...
