- noun a form of Java instructions that can be executed in a Java virtual machine. When a programmer develops a program written in Java, the Java compiler converts the instructions into a bytecode form that can then be run on any computer that supports the Virtual Machine software.
- An intermediate language which is processed by a virtual machine. The virtual machine converts the instructions into machine instructions most any CPU will understand, making such code essentially architecture-independent. For example, Java bytecode is processed by a Java Virtual Machine. Also spelled byte code. Also called pseudocode (3).
