Annotations In Java java Core Java by devs5003 - May 31, 2024June 2, 20245 Before the introduction of Annotations, we were extensively using XML for metadata. Using XML for metadata as configurations separates the configuration from the code. At the later stage, when enterprise applications grown up, maintenance of XML was getting inconvenienced. Also, XML loosely couples from the code, in some cases almost separates. Then architects & developers started looking for solutions which can be tightly coupled with the code instead of XML. Then the solution was an introduction to Annotations. Don't get confused with the fact that we should always prefer loose coupling as it differs in case of Annotations. You will feel the benefits almost always when you completely understand the topic 'Annotations In Java'. Just using an annotation instead of creating

Continuation-Passing Style-CPS in Java Core Java java Programming by devs5003 - May 15, 2024May 17, 20240 Continuation-Passing Style (CPS) is a programming model used to manage control flow in software applications. It provides a way to handle asynchronous or callback-based programming by explicitly passing control from one function to another. Although this concept was originally generalized in functional programming languages like Scheme, Haskell, and Scala, but CPS can also be implemented in object-oriented languages like Java. In this article, we'll analyze the concepts behind Continuation-Passing Style-CPS in Java and explore its implementation with code examples. What is Continuation-Passing Style? In traditional programming model, control flow is managed through the call stack. When a function is called, the current execution context is pushed onto the stack, and when the function returns, the context is popped off the stack, allowing
