📘 Core Java Day 13 | Synthetic Classes in Java Today learned about synthetic classes a concept that exists in Java even though we never write it in our code. - Synthetic classes are not written by developers - They are generated automatically by the compiler / JVM - Their bytecode is added behind the scenes - They are not visible in Java source code - We cannot directly create or modify them Where are synthetic classes used? Arrays in Java - When we create an array, Java does not expose any constructor Still, an object is created on the heap - This is possible because arrays are instances of JVM-generated synthetic classes Inner class access - Synthetic classes and methods are used to allow inner classes to access private members of outer classes Why are synthetic classes needed? - To simplify Java syntax for developers - To hide low-level implementation details - To maintain performance and safety - To support language features without exposing complexity

Object-Oriented Programming (OOP) in Java 🔥 Quick refresher on OOP in Java – the pillars that make Java powerful and reusable! Java is built around Object-Oriented Programming, with four core principles: Encapsulation: Bundle data and methods together, hiding implementation details (e.g., using private fields and public getters/setters). Inheritance: Allow classes to inherit properties from parent classes (extends keyword). Polymorphism: One interface, multiple implementations (method overriding or overloading). Abstraction: Hide complex details and show only essentials (abstract classes or interfaces). These concepts help write clean, maintainable code. What's your favorite OOP principle in Java, and why? #Java #OOP #Programming #JavaDeveloper #CodingTips

Today while practicing conditional statements in Java, I worked on a task to print the day of the week using a switch case. Most of us are familiar with the traditional switch-case that uses case, break, and default. But Java has an upgraded switch syntax that many developers are still not aware of 👇 Instead of writing multiple break statements, the modern switch allows us to use the arrow (->) syntax, which makes the code: ✔ cleaner ✔ more readable ✔ less error-prone Why I like this approach No need to worry about missing break Clear one-to-one mapping between case and output Better readability, especially for beginners Sharing this as part of my Full Stack Java learning journey — small concepts like these really help in writing modern, clean Java code. #FullStackJavaJourney #JavaLearning #LearningInPublic #JavaDeveloper #Notes Frontlines EduTech (FLM) Fayaz S Krishna Mantravadi Upendra Gulipilli Let me know your thoughts in the comments. Which switch syntax do you prefer — old or new?
