CODid you know that Java behaves differently when comparing wrapper classes like Integer? 🤯
In this quiz, we test a simple line of code:
Integer a = 128;
Integer b = 128;
System.out.println(a == b);
Most beginners expect true, but the correct output is: ❌
👇 Watch the video to learn why Java outputs false here!
This happens because of Integer caching mechanism in Java — only values between -128 to 127 are cached. Anything outside that range creates a new object, so == compares references, not values. 🧠💡

🎯 You'll Learn:
✔ Java wrapper class behavior
✔ Integer caching
✔ Difference between == and .equals()
✔ Common Java interview question

• It is open-source and free
• It is secure, fast and powerful
• It has a huge community support (tens of millions of developers)
• Java is an object oriented language which gives a clear structure to
