In this quiz, we test a simple line of code:
Integer a = 128;
Integer b = 128;
System.out.println(a == b);

This happens because of Integer caching mechanism in Java β only values between -128 to 127 are cached. Anything outside that range creates a new object, so == compares references, not values. π§ π‘
