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.
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
If you're starting from zero, don’t worry—you don’t need to be a computer wizard.
Your first move should be:
🔗 Java SE Programming I
This beginner course lays the foundation—syntax, variables, loops, logic. All the must-haves.
To keep up with the latest tech, aim for:
🔗 Java SE 21 Programming I
It’s ideal for developers ready to work on real-world projects using modern Java features.
Start with Java SE Programming I, level up with SE 21.
Not at all!
But understanding basic programming logic (like what a loop is or how variables work) will definitely make things easier.
Certifications can transform your CV from “cool” to “hire this person NOW.”
