💡 Java tip: Use Files.readString() and Files.writeString() for straightforward file I/O. #Java #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
💡Java tip: Use List.copyOf(list) for a safe, unmodifiable copy, while avoiding accidental changes. #Java #JavaDev
💡 Java tip: Starting from Java 8 you can use List.removeIf(<predicate>) to clean up collections in one line. #Java #JavaDev
💡 Java tip: Use Objects.requireNonNullElse(value, defaultValue) to avoid null checks. #Java #JavaDev
💡 Java tip: Use parallelStream() with care. It's ideal for CPU-intensive tasks, not I/O operations. #Java #JavaDev
🚀 You can use async logging in Spring Boot by configuring logback (logback-spring.xml). ✅ Log messages are sent into a queue, and are elaborated by a separate background thread. ✅ This reduces I/O bottlenecks. #SpringBoot #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
Java tip: Starting from Java 11, if you need to repeat n times a specific string, you can use the String method repeat(n). #Java #JavaDev
💡Java tip: Starting from Java 15 you can use String.formatted(...) for string formatting instead of String.format(...). #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
🚀 Spring Boot: In development phase, use spring.main.lazy-initialization=true to speed up the startup of the application. #SpringBoot #JavaDev
