These ready-to-use images allow us to easilyintegrate CRaC in a Spring Boot application: Improve Java application performance with CRaC support 1. Introduction In this tutorial, we’re going to explore different ways to start a thread and execute parallel tasks. This is very useful, in particul...
In Java, we can create aThreadin following ways: By extendingThreadclass By implementingRunnableinterface Using Lambda expressions 1.1. By ExtendingThreadClass To create a new thread, extend the class withThreadand override therun()method.
Threads in Java are lightweight processes that allow a program to run multiple tasks simultaneously. Learn what thread is, how to create them, and more.
Then, we will create a Thread and use the run() method we’ve just implemented within the Thread. Finally, we will start the Thread to execute asynchronously:public class AsynchronousCallback { public static void main(String[] args) { Runnable runnable = () -> System.out.println("Call...
