Looping through a Java list twice to get two different results? Use Collectors.teeing() (Java 12+). It acts like a T-pipe for streams: splits one dataset into two separate calculations (like Min & Max), then merges them at the end. One pass. Clean code. ☕️ #CtrlPlusCode #Java

Still writing 50 lines of Java boilerplate just to hold data? Java Records fix this in one line Behind the scenes, you instantly get: • Constructor • Getters • toString() • equals & hashCode Immutable & clean. #CtrlPlusCode #Java #Coding

Java trick seniors love ☕️💛 try-with-resources isn't just for files. Use it to auto-reset any state. Implement AutoCloseable, put cleanup in close(), and let Java handle the rest. It's guaranteed to run even if your code crashes. Bye, messy finally blocks! #CtrlPlusCode #Java

Spring AOP lets you inject logic (logging, security, transactions) into methods WITHOUT touching the actual code.💛 It wraps your bean in a proxy and intercepts calls. #CtrlPlusCode #Spring 🧵 Thread on how it works 👇

@Bean vs @Component in Spring.❤️‍🔥 @Component — You own the class, just annotate it and Spring auto-detects it via classpath scanning. @Bean — You don't own the class, so you manually instantiate and register it inside a @Configuration class. #CtrlPlusCode #Java #Coding
