Bytecode creates an extra level of indirection.
The advantages of this extra level of indirection are:
- Platform independence
- Can create any number of programming languages (syntax) and have them compile down to the same bytecode.
- Could easily create cross language converters
- x86, x64, and IA64 no longer need to be compiled as seperate binaries. Only the proper virtual machine needs to be installed.
- Each OS simply needs to create a virtual machine and it will have support for the same program.
- Just in time compilation allows you to update a program just by replacing a single patched source file. (Very beneficial for web pages)
Some of the disadvantages:
- Performance
- Easier to decompile

TaigaJava byte code helps portability as it allows any compter, with any system architecture to run the byte code. Instead of having to compile a java program to every different type of architecture or OS, the JVM (Java Virtual Machine) is compiled to each of the different architectures. This takes the burden off the programmer, allowing them to instantly create cross-platform code.

How many bytes does a Java VM have?
A JVM, or Java Virtual Machine, creates the environment in which programs that run using Java bytecode are processed. It does not itself possess bytes or bytecode.
Where does bytecode come from java?
It is created by the Java compiler, based on the source code (the .java file).
What do you get when you compile a java program?
The java interpreter or JVM (Java Virtual Machine) is not able to execute the java source code for a program. The java source code first needs to be compiled into bytecode that can be processed by JVM. Producing bytecode make the program platform independent as each platform has its own JVM. It is also possible to directly write bytecode, bypassing the need to compile, but that would be tedious job and also not good for security purpose as the compiler checks for various errors in a program.
What translates a Java program into Bytecode?
The Java Runtime Environment (JRE) converts the byte code to machine language.
Why java has compiler and interpreter both?
Java is both compiled and interpreted language.First Java source code has to be translated into Byte code, which is done with the help of a compiler.But these byte codes are not machine instructions. Therefore ,in second stage this byte code has to be translated into machine code.This task is performed by an Interpreter.Hence, Java use both compiler and interpreter.
