Jimmutable Collections: The inseparable collection of concurrent and thread security in the Java class library

Jimmutable Collections is a Java class library for processing concurrent and thread security.Uncharacteristic sets can provide high -performance and thread security characteristics in multi -threaded environments because they are not allowed to modify after creation.In this article, we will introduce the basic concepts, usage methods, and some Java code examples of Jimmutable Collections. What is an unsusted collection? Uncharacteristic collection refers to a collection that cannot be modified after creation.This means that once the collection is created, it cannot be added, deleted or modified.The uncharacteristic set is safe, because multiple threads can access the set at the same time without having to worry about the modification conflict of the data. Basic concept of Jimmutable Collections Jimmutable Collections Library is an open source project, which provides a set of unchanged collection classes that can be used to perform concurrent operations in a multi -threaded environment.These sets include commonly used data structures such as lists, mapping and sets.Jimmutable Collections provides some features that make them easy to use and efficient. Used Jimmutable Collections By using Jimmutable Collections, we can easily create and operate non -changing collection.First, we need to introduce the dependencies of the Jimmutable CollectionS library.If you use Maven, you can add the following dependencies to the pom.xml file: <dependency> <groupId>org.javimmutable</groupId> <artifactId>jimmutable-collections</artifactId> <version>4.4</version> </dependency> Create an unchanged list The following is a sample code to demonstrate how to create an unchanged list and add an element to it: import org.javimmutable.collections.*; public class ImmutableListExample { public static void main(String[] args) { JImmutableList<String> list = JImmutableList.of("apple", "banana", "orange"); System.out.println (list); // Output [Apple, Banana, Orange] JImmutableList<String> updatedList = list.insert("grape"); System.out.println(updatedList); // 输出 [apple, banana, orange, grape] } } Create unsusable mapping The following is a sample code to demonstrate how to create an unspeakable mapping (key value pair) and add elements to it: import org.javimmutable.collections.*; public class ImmutableMapExample { public static void main(String[] args) { JImmutableMap<String, Integer> map = JImmutableHashMap.<String, Integer>of() .assign("apple", 1) .assign("banana", 2) .assign("orange", 3); System.out.println (MAP); // Output {Apple = 1, Banana = 2, Orange = 3} JImmutableMap<String, Integer> updatedMap = map.assign("grape", 4); System.out.println(updatedMap); // 输出 {apple=1, banana=2, orange=3, grape=4} } } Other operations In addition to inserting elements, Jimmutable Collections also supports other common operations, such as deleting elements and obtaining set size.Detailed documents and examples can be found on the official website of Jimmutable Collection. in conclusion Jimmutable Collections is a Java class library for processing concurrent and thread security.It provides data structures such as efficient and easy -to -use unchanged lists, mapping and sets.By using Jimmutable Collections, we can obtain high -performance and thread security advantages in multi -threaded environment.
