Where is bytecode stored?

Where is bytecode stored?

• A. In a .java file
• B. In a .jar file
• C. In a .class file
• D. In a .exe file

Answer: (C)

Bytecode is the compiled form of Java source and lives in class files. When you compile a Java program, the compiler converts the .java text files into .class files that contain the JVM’s bytecode, which the Java Virtual Machine executes. A .java file is just the human-readable source code, not the bytecode. A .jar file is simply a packaged archive that can contain many .class files (and resources); it’s a convenient container, not the primary storage for the bytecode itself. An .exe is a Windows executable with native machine code, not Java bytecode. So, the bytecode-specific files are the .class files.
