Ctrl Plus Code

Roughly 67% of Java developers choose Spring Boot for their web development projects.💛 #CtrlPlusCode #Java

@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

Optional Class: In Java 8, the Optional<T> class was introduced in java.util to help avoid NullPointerException and make code more readable when dealing with values that may or may not be present💛 #CtrlPlusCode #Java #Coding

Gemini 3.5 Flash is built to help you execute complex, agentic workflows. 3.5 Flash rivals flagship models to deliver frontier performance for agents and coding, at the lightning speeds you expect from the Flash series.

❤️‍🔥Stream vs Parallel Stream in Java: ->Sequential Stream A sequential stream processes elements one at a time on a single thread. ->Parallel Stream A parallel stream splits the data into multiple sub-streams and processes them concurrently across multiple CPU cores. #CtrlPlusCode

Setter Injection in SPRING. When to use: -> Dependency is truly optional (required = false) -> Circular dependency workaround (rare) -> Reconfiguring bean after initialization #CtrlPlusCode #Java #Spring

Constructors Injection in SPRING. Why it's best: -> Fields can be final — immutable, thread-safe -> Easy to unit test — just new OrderService(mockPayment, mockNotif) -> Dependencies are explicit and visible #CtrlPlusCode #Java #Spring

Here is the Example for Field Injection. 💛 Problems: -> Can't make field final — no immutability -> Hard to unit test — can't inject mock via constructor -> Hides dependencies — not clear from outside what class needs #CtrlPlusCode #Java

Here is a simple @java Code to Prove 99^100 is the largest. 💛 #CtrlPlusCode #Java

Three Types of Autowiring in Spring: 1. Field Injection ❌ (Not Recommended) 2. Constructor Injection ✅ (Recommended) 3. Setter Injection ⚠️ (Use Only for Optional Dependencies) #CtrlPlusCode #Java #Coding

REQUEST MAPPING 💛 @RequestMapping("/api/users") ← applies to ALL methods below @GetMapping("/{id}") → GET /api/users/{id} @PostMapping → POST /api/users @PutMapping("/{id}") → PUT /api/users/{id} @DeleteMapping("/{id}") // → DELETE /api/users/{id} #CtrlPlusCode #Java

Dependency Injection (DI) in Spring Boot is a design pattern where an object's dependencies are provided by an external source (the Spring IoC container) rather than the object creating them itself. 🔥 #CtrlPlusCode #Java #developer

In the Spring Framework, IoC (Inversion of Control) is a core design principle where the responsibility of managing object lifecycles and dependencies is transferred from the developer to the framework.💛 #CtrlPlusCode #Java #developer

What is Spring Framework: The Spring Framework is an open-source, modular Java platform designed to simplify the development of complex enterprise applications. Core Concepts IoC & Dependency Injection, Aspect-Oriented Programming (AOP), Modular Architecture. #CtrlPlusCode
