What is bytecode?

• A. The final native machine code
• B. The source code written in Java
• C. The intermediate code produced after compiling Java source code
• D. The configuration file for the JVM

Answer: (C)

Bytecode is the intermediate code produced after compiling Java source code. When you write Java and run it, the compiler translates your .java files into .class files that contain bytecode. This form is designed to be portable across platforms, so the same bytecode can run on any device with a JVM. At runtime, the JVM either interprets this bytecode or JIT-compiles hot parts into native machine code for the host CPU. This portability is why Java programs can run on different operating systems without recompilation. The other descriptions refer to what the compiler does not produce: the final native machine code that runs directly on hardware, the original Java source, or a configuration file for the JVM.
