Chapter II: lambda expression
The biggest change in Java8 is the introduction of lambda expressions, a compact way of passing behavior, which is what's left of the book, so let's go into it.
Write the first lambda expression
Swing is a platform-independent GUI library in which there are many common habits, such as registering an event listener to know what th
[Java 8] Lambda expressions optimize recursion (I) and lambda expressionsRecursive Optimization
Many algorithms rely on recursion, such as Divide-and-Conquer ). However, StackOverflowError often occurs when a common recursive algorithm is used to deal with large-scale problems. To solve this problem, we can use a techn
its object, in this way, we pass some function functions to the Addmouselistener method.
In short, it's not easy to pass a normal method or function as a parameter in Java, and Java 8 adds a new language-level feature called a Lambda expression .
Why does Java
After understanding some of the basic concepts and applications of Java 8 Lambda, we have a question: what is a lambda expression compiled into? This is an interesting question that involves the specific implementation of the JDK. This article introduces the details of OpenJDK's conversion to

1. What is a Lambda expression?
Lambda expressions are essentially an anonymous method. Let's take a look at the following example:
Public int add (int x, int y ){Return x + y;}

to verify members ' personal information or get information about their contacts? In this case, you need a functional interface with an abstract function that has a return value. The Function interface contains a R apply(T t) method with a parameter and a return value. The following method gets the data that the parameter matches to, and then handles the corresponding lambda expression code block:public static void processPersonsWithFunction( List
"Editor's note" Although Java has won a lot of developers love, but compared to other modern programming languages, its syntax is indeed slightly lengthy. But with Java8, you can write code that is both readable and concise by using lambda expressions directly. The author Hussachai Puripunpinyo's software engineer, who analyzed the differences in performance and expression by comparing

Example 1, using lambda expression to implement runnableWhen I started using Java 8 o'clock, the first thing I did was to replace the anonymous class with a lambda expression, and the implementation of the Runnable interface was the best example of an anonymous class. Take a look at the runnable implementation before

Hussachai Puripunpinyo considers Java as a static strong-type language. Therefore, although Java 8 has become a first-class citizen, it can be passed as a function parameter or ret
Why?Why do we need lambda expressions?There are three main reasons:> More compact codeFor example, the existing anonymous internal classes in Java, as well as listeners and handlers are all very lengthy.> Ability to modify methods (I personally think it is code injection, or a bit similar to a callback function in JavaScript to another function)For example, the contains method of the collection interface re
