From Code to Cloud: My Learnings in Java, Spring Boot, and Beyond

  Enhancements in Java 8 for Concurrency and Multithreading Java 8 introduced several enhancements and new features to improve concurrency and multithreading. Among these, CompletableFuture stands out as a powerful tool for asynchronous programming. This post explores the key additions in Java 8 related to concurrency, including CompletableFuture , runAsync() , supplyAsync() , and other notable features. CompletableFuture CompletableFuture is a class that implements the Future interface and provides a flexible way to handle asynchronous computation. It allows you to write non-blocking code and provides a variety of methods to create, combine, and process asynchronous tasks. Key Methods runAsync() The runAsync() method is used to run a task asynchronously without returning any result. CompletableFuture<Void> future = CompletableFuture.runAsync(() -> { // Task to run asynchronously }); supplyAsync() The supplyAsync() method is used to run a task asynchronously that...

  Java 8 New Features: Embracing Functional Programming in Java Java 8 marked a significant shift in the Java programming language by introducing powerful features that embraced functional programming paradigms, enhanced API design, and simplified coding practices. In this post, we explore the major features introduced in Java 8 and how they revolutionized the Java ecosystem. Key Features in Java 8 Lambda Expressions Functional Interfaces Method References Default Methods Optional Stream API Lambda Expressions Lambda expressions provide a concise way to represent functional interfaces (interfaces with a single abstract method). This enables passing functionality as an argument to methods. Syntax: (parameter1, parameter2) -> expression Examples: (int x, int y) -> x + y () -> 42 (String s) -> { System.out.println(s); } Example - Runnable Lambda: Runnable r = () -> System.out.println("Hello from lambda"); new Thread(r).start(); Advantages: Reduces boilerplate code...
