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

__🔥 Java String Reality Check — 99% Answer This Wrong 😈💻
These questions don’t test memory… they test how Java actually works ⚠️
1️⃣ Output: true
"Ja" + "va" is a compile-time constant.
Both strings point to the same object in the String Constant Pool 🧠
2️⃣ Output: Empty String
substring(1, 1) means start and end index are the same.
No characters → empty result, not an error 👀
3️⃣ Output: nullDev
When null is concatenated with a String,
Java converts it to the text "null" automatically 😳
If you got all 3 without running the code…
You actually understand Java Strings 🔥

CODay 1/30: Why is "Java" == "Java" FALSE? 😱
Starting a 30-day journey to master Java Logic! 🚀
Most beginners get confused here. In Java, the == operator doesn't check the content; it checks the Memory Address.
📍 The Logic:
When you use literals (""), Java looks in the String Constant Pool to save memory.
When you use new, Java is forced to create a brand new object in the Heap.
Since they live in different parts of the memory, their addresses don't match!
Want to check the value instead? Use .equals().
