The buzz around Python is high, especially with the rise of AI, but dont count out Java In fact, a
whopping 90 of Fortune 500 companies still rely on Java. These arent small businesses Fortune
500 lists the top 500 companies by revenue each year. Need to check if a company uses Java
Simply go to their careers page and search for Java in their job postings easy While many MNCs
Multinational Corporations utilize Java, its important to understand why.
Java isnt slowing down its consistently a fast and reliable language. Java developers command
comparable salaries to Python developers, averaging around 7 Lakhs per annum. The
opportunities are vast: you can become a Mobile Application Developer, a Full-Stack Web
Developer, or a Back-End Developer the scope is tremendous. Java allows you to accomplish
tasks that are difficult, or even impossible, with Python. Think secure web pages - most banking
websites are built on Java due to its robust security features.
The instructors personal favorite Java. Despite acknowledging its initial complexity Jav actually
is a difficult language, they emphasize that understanding the fundamentals, which theyll break
down in this series, makes it accessible. Learning Java first often makes picking up other
languages easier.
Lets dive into how Java actually works. The process can be visualized like this:
You Write Code: In Visual Studio Code VS Code, you write code, like System.out.printlnHello
World;.
Compilation: The Java Compiler translates your readable English-like code into
bytecodemachine-readable instructions. Think of it as converting a message into a secret code.
JVM Execution: This bytecode isnt directly understood by your computer. It needs the Java
Virtual Machine JVM. The JVM acts as an interpreter, translating the bytecode into instructions
your computer understands and then executing them.
Visual Analogy: Input English Code - Compiler - Bytecode - JVM - Output Result
