What is Java's main advantage?

Java's primary advantage is its ability to allow programmers to write code once and run it anywhere. This is known as "Write Once, Run Anywhere" or "WORA".

What is Java bytecode?

Java bytecode is an intermediate language created by compiling Java source code. It is platform-independent, meaning it can run on any Java Virtual Machine (JVM) regardless of the underlying operating system or hardware.

Who created Java?

Java was created by James Gosling and his team at Sun Microsystems, now owned by Oracle.

When was Java released?

Java was first released in 1995.
