Learn Kotlinx Coroutines Core framework: Treatment of concurrent tasks in the Java library introduction: In the field of software development today, it is inevitable to deal with concurrent tasks.To simplify the complexity of concurrent programming, Kotlin introduced Kotlinx Coroutines Core framework.This article will introduce the basic concepts, usage methods and related configurations of the Kotlinx Coroutines Core framework. It provides corporate concurrent primitive and related tool functions, allowing developers to process concurrent tasks in non -blocking ways to avoid traditional callback hell and complex thread management. The basic concepts and usage of Kotlinx Coroutines Core: 2. Coroutine Dispatcher: The coroutine scheduler is responsible for when, where, and which thread is restored to the coroutine.It can schedule the coroutine to different thread pools or specified threads. 3. Hanging function (Suspending Function): Hanging function is a function that can suspend coronance and continue to execute at a suitable time.It can perform tasks asynchronously without blocking the current thread. 4. Asynchronous and sequential tasks: Kotlinx Coroutines Core provides a simple way to deal with asynchronous and sequential tasks.By using ASYNC functions to create asynchronous tasks and AWAIT functions waiting for their completion, developers can easily handle concurrent tasks. Configuration of Kotlinx Coroutines Core: To use Kotlinx Coroutines Core in the Java library, the following configuration needs to be performed: 1. Add dependencies: First, make sure to add the dependencies of the Kotlinx Coroutines Core to the project construction file.In the Gradle project, you can add dependencies like the following: groovy dependencies { implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.0" } 2. COROUTINESCOPE: In order to use coroutines, we need to create an coroutine scope.The coroutine scope tracks all relevant coroutines during the execution of the coroutine and provides the ability to cancel the coroutine. CoroutineScope myScope = new CoroutineScope(Dispatchers.Default); 3. Define a hanging function: Create a hanging function for the code block that needs to be performed asynchronous.You can use the function of the `Suspend` keywords. public suspend void doAsyncTask() { // The task of asynchronous execution } 4. Start a coroutine: Use the `launch` function to start a coroutine in the coroutine field, and call the previously defined hanging function. myScope.launch { doAsyncTask(); } 5. Use asynchronous tasks: In order to perform asynchronous tasks and wait for it to complete, you can use the `Async` function. Deferred<String> result = myScope.async { // The task of asynchronous execution and return the result Return "task is completed" } myScope.launch { String resultString = result.await(); // process result } Summarize: The Kotlinx Coroutines Core framework provides a simple and easy way to process concurrency in the Java class library.By understanding basic concepts and configurations, developers can start using corporate to simplify concurrent programming to improve the readability and maintenance of code.
