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. ☕️

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.

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!

String Compression 💛
The Goal: Implement a method to perform basic string compression using the counts of repeated characters.
For example, the string aabcccccaaa would become a2b1c5a3.
Time Complexity: O(n + k)

Most used Design Patterns in Java:
Singleton → one instance (watch out in multithreading)
Factory → delegate object creation
Builder → clean object construction
Observer → event-driven logic
Strategy → swap algorithms at runtime
Spring uses all 5 internally.

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.

🧵 Thread on how it works 👇

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

@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.

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💛

❤️🔥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.

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

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

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

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

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}

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.
