bytecode code example

Example 1: what is bytecode in java

When a javac compiler compiler compiles a class it generates .class file. 
This .class file contains set of
instructions called byte code. Byte code is a machine independent language 
and contains set of
instructions which are to be executed only by JVM. JVM can understand 
this byte codes.

Example 2: byte code

Bytecode is program code that has been compiled from source code into low-level code designed for a software interpreter. It may be executed by a virtual machine (such as a JVM) or further compiled into machine code

Example 3: bytecode

6      5     5     5     5      6 bits
[  op  |  rs |  rt |  rd |shamt| fonct]  type-R
[  op  |  rs |  rt | adresse/immédiat ]  type-I
[  op  |        adresse cible         ]  type-J
