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

🚀 Spring Boot: Spring Data JPA has a built-in support for pagination with Pageable. ✅You should use pagination in your repositories instead of fetching all. #SpringBoot #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

Java tip: Starting from Java 9 you can use Stream.takeWhile() for easy slicing of lists by streams. #Java #JavaDev

💡 Java tip: Starting from Java 8, you can remove nulls easily with list.removeIf(Objects::isNull). #Java #JavaDev

🚀 Spring Boot tip: With Spring Boot and Spring Security you can secure endpoints easily. #SpringBoot #JavaDev

💡Java: If you need to write OS-native newlines, you can use System.lineSeparator(). #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

Use of @Profile in Spring Boot Spring Boot supports @Profile to define environment-specific beans. Use it to activate performance profiling tools or logging only in development. Helps keep production clean and fast. #SpringTips #JavaDev #ayshirv

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

🚀Spring Boot: Adding request tracing IDs is important for debugging APIs #SpringBoot #JavaDev

💡Java tip: Starting from Java 14 you can use switch expressions for shorter and cleaner multi-branch logic. #Java #JavaDev

Java tip💡: If you have a list of elements, you want to remove duplicates, and sort them in natural order or by a custom comparator, you can use TreeSet. #Java #JavaDev

💡 SOLID Principles: Interface Segregation Principle (ISP) states that clients shouldn’t depend on methods they don’t use. ✅ Large, general-purpose interfaces should be broken down into smaller, more specific ones. #Java #JavaDev

💡 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

💡Spring Boot tip: Use H2 if you need an in-memory database for dev/testing. #SpringBoot #JavaDev

Why use JWT Why use JWT in your app? No need to store session - Secure and fast - Works well with REST APIs - Easy to use with Spring Boot #JavaDev #JWT #SpringBoot #ayshriv

💡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
