　　Recently because of the project needs, just finished learning the action delegate and FuncLambda expressionA lambda expression is an anonymous function, an efficient expression similar to functional programming, and lambda simplifies the amount of code that needs to be written in development. It can contain expressions and statements, and can be used to create delegates or expression tree types, and suppo

Http://msdn.microsoft.com/zh-cn/library/bb397687.aspx A LAMBDA expression is an anonymous function that can be used to create a delegate or an expression tree type.By using a lambda expression, you can write a local function that can be passed as a parameter or returned as a function call value. Lambda expressions are especially useful for writing LINQ query ex

Lambda through the previous article we can basically see that lambda is a behavior very similar to the anonymous inner class of something, and in fact, most of the time it is to replace the anonymous inner class to achieve a more concise syntax. You can see that this is a simple example of using LAMBDA instead of Comparator anonymous classes for sorting. First o

If provided, it is usually a comma-separated variable expression form, that is, the location parameter. Expression: it cannot contain branc

Anonymous functions: Lambda expressions, anonymous methods, and lambda expressions An "inline" statement or expression of an anonymous function, which can be used wherever the delegate type is required. You can use an anonymous function to initialize the name delegate, or pass the name delegate (instead of the name delegate type) as the method parameter. There are two types of anonymous functions:

Java --> Lambda expressions, java -- lambda expressionsI. functional interfaces Function interfaces (functional interfaces are also called functional interfaces. They are actually the same thing ). To put it simply, a functional interface contains only one method. For example, Java. lang. Runnable and java. util. Comparator in the java standard library are typical functional interfaces.Java 8 provides @ F
