How I Learned #Java in Depth by preparing for #Java Technical Interviews #javadev #dormosheio

Spring Boot makes you feel like you’re doing a lot less, but actually building a lot more. That’s framework design done right. #JavaDev #SpringBoot #ayshriv

Mastering #Java Stream API in Java: From Basics to Best Practices #javaprogramming #javadev #dormosheio #bestpractices

💡 Java: Records are not limited to data only, you can add custom constructors or methods for validation. ✅ They can have constructors, static methods, and instance methods: #Java #JavaDev

🚀 JUnit 5 Tip 🚀 Since JUnit 5, leverage package-private visibility for classes and methods to enhance encapsulation in your tests. This helps keep your testing logic close to the code it's testing while maintaining a clean and organized codebase. #JUnit #Testing #JavaDev

💡Spring Boot tip: If you need to implement integrations tests for Spring MVC controllers, and mock everything else, use @WebMvcTest to load only MVC-related beans. #SpringBoot #JavaDev

Getting back on track with Java. Implemented a HashMap today and revised its core operations. More to come. #BackToCode #JavaDev

Java tip : Starting from Java 19 you can explore a feature called "virtual threads". ✅ Virtual threads are lightweight threads managed by the JVM rather than the OS. #Java #JavaDev

Spring Batch makes ETL tasks easy to manage. Just define jobs, steps, and chunks — and it handles everything else. It also manages transactions, retries, and job status by default. #DevLife #JavaDev #SpringBatch #ayshriv

💡Java Tip : Prefer constructor injection over field injection. #Java #JavaDev

🚀 Open/Closed Principle (OCP): OCP is a SOLID principle that states classes should be open for extension but closed for modification. ✅Instead of touching existing implementation, you should use Java interfaces and inheritance to add new behavior. #Java #JavaDev

💡Java: Use Deque instead of Stack for LIFO (last-in, first-out) lists. ✅ Stack is a legacy class, it extends Vector and synchronizes every operation ✅ Deque supports the same push, pop, peek calls ✅ ArrayDeque is faster than Stack #JavaDev

Spring Boot: Everything you need to know, and what nobody told you. Part I #java #javaprogramming #javadev #dormosheio #springboot #expert #programming

🚀 Spring Boot: @TransactionalEventListener can be used to implement post-commit actions. #SpringBoot #JavaDev 🧵A full article with an example to follow

💡 Spring Boot: To better handle circular dependencies, use constructor injection instead of field injection. ✅ Forces all required dependencies to be provided at creation time, allowing early detection. #SpringBoot #JavaDev

🚀 Java: Use ReentrantReadWriteLock Java concurrence utility if you have to deal with frequent reads and fewer writes. #Java #JavaDev

Java Tip 💡: Use Files.walk() to recursively process files in a directory. #Java #JavaDev

💡 Java tip: Use Duration and Instant for precise time calculations. #Java #JavaDev
