functional interface.See, Lambda and functional interfaces appear, and the function interface itself is for lambda service.So, what is a functional interface? It is simply that an interface (abstract class) has only one method to implement, and we are called a functional interface.To express this concept, an annotation is used to express the concept in Java8, public @interface Functionalinterface {}This annotation is just a markup annotation, and the only thing that can be provided is to indica

derivation of Swift. In fact, the type defined on the left side of the code is just the type that the programmer wants, and the right side is the type of the program . That is, the type of the variable or constant will derive the corresponding type according to the result of the right-hand code execution.You can use the Hotkey option to click View Type. Strict: in swift, no direct operation is allowed between any different types of data .If you want to allow operations between different types
