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

🔥Get Started
It is not necessary to have any prior programming experience.
🔥What is Java?
Java is a popular programming language, created in 1995.It is owned by Oracle, and more than 3 billion devices run Java.
🔥It is used for:
• Mobile applications (specially Android apps)
• Desktop applications
• Web applications
• Web servers and application servers
• Games
• Database connection
• And much, much more!
🔥Why Use Java?
• Java works on different platforms (Windows, Mac, Linux, Raspberry Pi,
etc.)
• It is one of the most popular programming language in the world
• It has a large demand in the current job market
• It is easy to learn and simple to use
• 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
programs and allows code to be reused, lowering development costs
• As Java is close to C++ and C#, it makes it easy for programmers to
switch to Java or vice versa
🔥Java Install
download it for free at oracle.com.
Setup for Windows
1. Go to "System Properties" (Can be found on Control Panel > System and
Security > System > Advanced System Settings)
2. Click on the "Environment variables" button under the "Advanced" tab
3. Then, select the "Path" variable in System variables and click on the
"Edit" button
4. Click on the "New" button and add the path where Java is installed,
followed by \bin. By default, Java is installed in C:\Program
Files\Java\jdk-11.0.1 (If nothing else was specified when you installed it).
In that case, You will have to add a new path with: C:\Program
Files\Java\jdk-11.0.1\bin
Then, click "OK", and save the settings
5. At last, open Command Prompt (cmd.exe) and type java -version to see
if Java is running on your machine

IMSave this so you don’t forget 💡
If you want to learn Java, you have a few options:
1. If you prefer books, then I’d recommend ‘Head First Java’. You can find the link for this in my bio 🔥 It is a really good book that covers essential Java programming concepts including classes, objects, threads, collections, and other language features such as generics, enums, variable arguments and auto-boxing. They also have an advanced section on Swing, networking and Java IO. It makes it a complete package for Java beginners. This should be your first Java book if you’re starting from scratch.
2. If you have more time and want to learn from someone who’s fun, interactive and gives sweets to his students when they get the answers right; then I highly recommend ‘Programming Methodology’ by Stanford on YouTube. It is taught by Professor Mehran Sahami and you don’t have to watch all the lectures. He explains things so well and although the lectures are old, you will learn so much in a short space of time. You can use this alongside the ‘Head First Java’ book above.
3. If you want something more challenging with a focus on getting a programming job, check out ‘Object Oriented Java Programming: Data Structures and Beyond Specialization’ on Coursera. You can enrol for free (without the certificate). In there you’ll learn object oriented programming in Java and quickly move onto data structures and algorithms as well as mastering the software engineering interview - all in Java. This is highly useful if you need to apply for a Java engineering job at a bigger tech company soon.
