What is the difference between machine language code and byte code?
Expert Solution & Answer
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. |
