Chapter 1, Problem 11SA

What is the difference between machine language code and byte code?

Explanation of Solution

Machine Language:

• Machine language is also called as object code.
• The machine language varies from operating system (OS) to another.

Byte code:

Java program is the high-level language. So, java compiler is used to compile the java program (high-level language) into java bytecode (standard machine code).

Difference between machine language code and byte code:

Machine Language code	Byte code
Machine language is also called as object code.	The Java compiler generates the source code into “Bytecode”.
It is executed directly by CPU. It is in binary format.	The JVM (Java Virtual Machine) interpreter is designed to execute the bytecode program produced by the compiler.
It is difficult for humans to read and write. But, it is easily understood by computers.	The interpreter takes the bytecode to convert the machine code and executes it.
