Introduction Spring AOP (Aspect Oriented Programming) compliments OOPs as it also provides modularity. But The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect. AOP breaks the program logic into distinct parts (called concerns). It is used to increase modularity by cross-cutting concerns such as transaction management, […]
Welcome to our comprehensive guide on Multithreading and Synchronization! In this page, we will delve into the fascinating world of concurrent programming and explore the essential concepts, techniques, and best practices for effectively managing multiple threads in your applications. Multithreading is a powerful paradigm that allows programs to execute multiple tasks concurrently, thereby utilizing the

IOC Container Spring IoC (Inversion of Control) Container is the core of Spring Framework. It creates the objects, configures and assembles their dependencies, manages their entire life cycle. It receives instructions about the same from the provided configuration metadata. and uses Dependency Injection(DI) to manage the components that make up the application. Means for providing the

A semaphore controls access to a shared resource through the use of a counter. What the counter is counting are permits that allow access to the shared resource. Thus, to access the resource, a thread must be granted a permit from the semaphore. Synchronized allows only one thread of execution to access the resource at the same time. Semaphore
The lock interface is one of the most used interfaces in Java. Lock interface is available in the Java.util.concurrent.locks package which we use as a thread synchronization mechanism, i.e., similar to synchronized blocks. It is more flexible and provides more options in comparison to the synchronized block. It allows us to gain the benefit of fine-grained locking without having
Java concurrency API includes the executor framework since java 5 to improve the performance of concurrent applications with a lot of concurrent tasks. It is a mechanism that allows you to separate thread creation and management for the implementation of concurrent tasks. You don’t have to worry about the creation and management of threads, only

Synchronization is the coordination of two or more tasks to get the desired results. We have two kinds of synchronization: synchronization helps you avoid some errors you can have with concurrent tasks but it introduces some overhead. You have to calculate very carefully the number of tasks, which can be performed independently without intercommunication in

When we create an application, we write lines of code and logic is also correct. But still we wonder that our application is not upto the mark. One important factor that plays a vital role in any application development is its Performance.However the performance of an app is not only related to the number of
41. What is the role of web and RESTful APIs in Microservices?A microservice architecture is based on a concept wherein all its services should be able to interact with each other to build a business functionality. So, to achieve this, each microservice must have an interface. This makes the web API a very important enabler
