How I fixed a Spring Boot memory leak While debugging an API latency spike, I found an object with improper scope in a singleton bean — classic memory leak pattern. Use @RequestScope for heavy per-request objects, not @Component #SpringBoot #MemoryManagement #JavaBackend #Tips

🚦 Say goodbye to annotation overload. ActiveJ takes a pragmatic, no-nonsense approach to Java backend development. #JavaBackend

Day 2/20 of #JavaBackend Topics i have done today : - learned Spring MVC, Layers (Controller, Service, Repository) - learned Spring Data JPA - made CRUD APIs for product using it.

Day 1/20 of #JavaBackend Topics i have learned today are - IoC & DI - Annotations like Component, Bean, Autowired etc usefull for DI - made Simple API using Controller and RestController - got to know about modules like service, controller, repository, for Architecture.

Reducing Java Docker image size by switching from JDK to JRE can drastically improve startup time, like significant improvement... #Docker #JavaBackend #Containerization #Java

🔥 Data Types in Java In Java, data types specify the type of data that a variable can hold. They are divided into two main categories: 1. Primitive Data Types Data Type -------------- - byte (Small integer (-128 to 127)) - short (Medium integer (-32,768 to 32,767)) - int (Large integer (-2^31 to 2^31-1)) - long (Very large integer (-2^63 to 2^63-1)) - float (Decimal numbers (6-7 digits precision)) - double (Decimal numbers (15 digits precision)) - char (Single character) - boolean (True or False) 2. Non-Primitive Data Types (Reference Types) Data Type -------------- - String (Sequence of characters) - Array (Collection of similar data types) - Class (Blueprint for objects) - Interface (Collection of abstract methods) #Java #JavaProgramming #JavaTutorial #JavaDeveloper #LearnJava #JavaForBeginners #JavaOOP #JavaCollections #JavaBackend #JavaFramework #SpringBoot #JavaMultithreading #JavaDesignPatterns #Java2025 #JavaLambda #JavaStreams #JavaFunctionalProgramming #JavaWithSpringBoot #JavaCoding #Coder #JavaProject #JavaBackendDeveloper #JavaDevelopment #JavaCodingChallenge #react #developer

Day 29 : #JavaBackend : Started my journey into Java backend development today! Excited to dive into server-side logic and databases. It’s a new challenge, and I’m ready to push my skills to the next level, from scratch!!! #Coding #Java #BackendDevelopment

Not much new functionality today, have been slowly working on fixing small components to work with my new caching system. However, I did manage to add an emoji picker for posts!😎🔥 #ReactJS #BuildInPublic #JavaBackend #WebDevProject #WebDevelopment

Managed to add functionality to upload images with posts😎🔥📸 The images are stored in a post_media SQL table, and each picture contains a foreign key with its original post_id. My next step is compressing the images. #Java #JavaBackend #WebDevelopment #WebDevProject #ReactJS

Have been working on implementing notifications, which was more difficult than it seemed. So far only have liked posts, but I kind of spaghetti'd my code by putting the add like notification logic in the like class (instead of its own class). #Javabackend #backend
