Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Platform independence is the key.
Java source code (`.java` files) is compiled by the javac compiler into bytecode (`.class` files). This bytecode runs on the Java Virtual Machine (JVM), which is platform-specific but makes Java programs portable across any system with a JVM installed.
↳ Java achieves portability by compiling to bytecode, executed by the JVM.
Know the difference to save time.
↳ JDK is for development; JRE is for running; JVM is the engine inside both.
Every Java app starts here.
The JVM looks for this exact signature to begin execution. `public` makes it accessible; `static` allows calling without an object; `void` returns nothing; `String[] args` holds command-line arguments.
↳ The `main` method is the mandatory starting point for any standalone Java application.
Java is a statically typed, object-oriented language that achieves platform independence by compiling source code to bytecode, which runs on the Java Virtual Machine (JVM). Key fundamentals include the eight primitive da...
