Top 10 Java Multithreading and Concurrency Best Practices

Writing concurrent code is hard and testing correctness with concurrency is even harder. Though Java programming language provides lots of synchronization and concurrency support from language to API level, it eventually comes to an individual's diligence and expertise to write bug-free Java concurrency code. These Java concurrency and multi-threading best practices are a collection of some well-known tips, which help you to write better concurrency code in Java. Some of you may be familiar with these tips but it's often worth revising them time and time again. 

10 Object-Oriented (OOP) Design Principles Java Programmers Should Know

The Object-Oriented Design Principles are the core of OOP programming, but I have seen most of the Java programmers chasing design patterns like Singleton pattern, Decorator pattern, or Observer pattern, and not putting enough attention on learning Object-oriented analysis and design. It's essential to learn the basics of Object-oriented programming like Abstraction, Encapsulation, Polymorphism, and Inheritance. But, at the same time, it's equally important to know object-oriented design principles. They will help you to create a clean and modular design, which would be easy to test, debug, and maintain in the future.

Top 5 NoSQL Databases Programmers Should Learn in 2021

Though it's not mandatory for Java or Web developers to learn the NoSQL database, the world is moving in that direction, and both Java and Web developer should be familiar with NoSQL databases.

10 Tools Used by Java Programmers in Day to day life

Every trade has its tools, and Java programming is no exception. In fact, good knowledge of tools and mastery of using them saves a lot of time in design, development, testing, debugging, and troubleshooting any production issue. To become a good developer, you must know the right tools for the right jobs. A developer without tools and tricks is like a toothless lion; hence you must devote some time to learning the tools required for your day-to-day job. Many developers think that learning an IDE like Eclipse, NetBeans, or IntelliJ IDEA is enough, but that's just the start of the process. No doubt that IDEs are the most important tool ever created for programmers, but they are not the solution for everything.

There is no doubt that the Spring Framework is one of the most popular Java frameworks and makes it really easy to create real-world, enterprise-grade Java applications easy by providing features like dependency injection and inversion of control. But, to be honest, Spring is much more than just another DI and IOC framework.
