What Exactly Is Java Technology? (The Basics Explained Simply)
Java is a programming language and computing platform first released by Sun Microsystems in 1995 (now owned by Oracle).
Think of Java as a toolbox that developers use to create:
Android mobile apps
Banking and financial systems
E-commerce platforms like Amazon & Flipkart
Cloud-based solutions and enterprise applications
Why Is Java Special?
Unlike many other programming languages, Java follows the principle of:
“Write Once, Run Anywhere” (WORA).
This means if you write a program in Java, it can run on any computer, phone, or device—without needing big changes.
👉 Visual Suggestion: Insert a flowchart showing how Java code works:
1. Write Java Code
2. Compile into Bytecode
3. Run on Java Virtual Machine (JVM)
4. Works across Windows, Mac, Linux, Android
