In Java, logging can be done using various frameworks, with the Java Util Logging (JUL), Log4j, and SLF4J (with Logback) being among the most popular. Here’s a tutorial on logging in Java using…

Java introduced method references in Java 8 as a part of the lambda expressions feature. Method references provide a shorthand syntax to refer to methods without having to explicitly invoke them. This can make your code cleaner and easier to read. What are Method References? Method references are a way to refer to a…

Introduction Java 8 introduced significant enhancements to the language, including Streams and CompletableFuture. These features facilitate more efficient and expressive coding, particularly when handling collections and asynchronous computations. Combining Streams and CompletableFuture can lead to powerful and elegant solutions to complex problems. This article explores practical examples of how to combine these two features…

Introduction Java 8 introduced functional interfaces and lambda expressions, transforming the way developers write and approach Java code. A functional interface is an interface with a single abstract method, allowing for more streamlined and functional programming. This article will guide you through the concept of functional interfaces, their significance, and provide step-by-step examples to…

Introduction Lambda expressions, introduced in Java 8, are a powerful feature that allows developers to write concise and expressive code. They enable you to treat functionality as a method argument or pass a block of code around. Lambda expressions are a key feature of functional programming in Java, facilitating cleaner and more readable code,…
