Relation to Java[edit] Bytecode is the intermediate representation of a Java program, allowing a JVM to translate a program into machine-level assembly instructions. When a Java program is compiled, bytecode is generated in the form of a .class file. This .classfile contains non-runnable instructions and relies on a JVM to be interpreted.
