1.LAMBDA Expressions-background knowledge and related evaluations:Lambda expressions allow you to replace a functional interface with an expression.Function programming is fully embodied in C #, Python, and JavaScript. Java until the latest Java 8 began to formally support functional programming, the most obvious improvement is the support of Lamba expression. As C # 's father Anders Hejlsberg in the main trend of programming languages, the future pro

First, the lambda function1. Basic lambda function:The lambda function is also called an anonymous function, that is, the function does not have a specific name, and the method created with Def is a name.

Otherwise, you can learn Guido van Rossums prefers to use the "list comprehensions" (Recursive construction list), because he also doesn't like Lambda, ma

protected, so it is necessary to redefine it as public in the implementation class in order to invoke the Clone method of the instantiated implementation class object in other classes.The Cloneable interface is a markup interface, and the markup interface does not contain any methods; its only function is to allow the use of instanceof in type queriesIf clone is called on an object, but the class of the object does not implement the Cloneable interface, the Clone method of object class throws a
