Binary Class
- The binary class format is defined in the JVM spec. So compatible class files can be produced from any language definition.
- Every binary class starts with the "cafe babe" signature.
- Class format version numbers - minor and major.
- Bytecode is machine code for the JVM.
- The JVM uses a stack architecture with instruction operands being loaded onto an internal stack.
- Early JVM's were interpreters - Next gen JVM's added JIT to compile bytecode to native code.
