Try this 🤔 Integer a = 100; Integer b = 100; System.out.println( a == b) // true Integer x = 200; Integer y = 200; // false you know why?! #Java #Programming 👇

Welcome to the Integer Pool! Java has a secret: the Integer Pool! Think of it like a special VIP lounge for small, frequently used numbers (typically -128 to 127). Java pre-creates and reuses these exact Integer objects to be super efficient.

Why Bother? There are two big reasons for developers: Memory Saving: No need to create new objects for the number 5 a million times. Performance Boost: Less object creation overhead. It's Java being smart with resources! Does your code need this kind of optimization?

How it Works (Autoboxing) When you use Integer.valueOf(10) or simply Integer i = 10; (autoboxing), Java peeks into this lounge. If 10 is there, it hands you the existing object. If it's 200, it says, "Sorry, you need a new one!"
