Think Integer a = 128; Integer b = 128; a == b is true?
❌ Think again!

Java has a hidden feature called Integer Caching where values from -128 to 127 are cached. This means Integer a = 127; Integer b = 127; a == b will be true, but Integer c = 128; Integer d = 128; c == d will be false.

This is one of the most asked Java interview questions, and surprisingly, most developers get it wrong because they confuse == (reference check) with .equals() (value check).

👉 Learn this once and never fall for it again!
