What is Java? Where to Start & 10 Things You Need to Know Before You Begin!

Java Explained (The Simple Way)

Java is an object-oriented, open-source programming language known for its famous motto:

“Write once, run anywhere.”

Thanks to the Java Virtual Machine (JVM), Java applications run across different platforms—Windows, Linux, macOS… you name it. Same code, multiple environments. No rewriting. No drama.

Why Is Java Still So Popular?

Because it’s built to last:

JVM makes it platform-independent
It's open-source with massive community support
Powers Android apps, enterprise systems, web services
Offers a HUGE ecosystem of libraries and frameworks

Your first move should be:

To keep up with the latest tech, aim for:
🔗 Java SE 21 Programming I
