What is difference between machine code and bytecode?
Byte code is a non-runnable code generated after compilation of source code and it relies on an interpreter to get executed. Machine code is a set of instructions in machine language or in binary format and it is directly executed by CPU.
What is difference between bytecode and object code?
Object code – a package of code to be executed that can be manipulated by (usually) a linker to produce a program or a library, or which can be an input to a loader. The packaged code is generally either byte code or machine code.
Why bytecode is called bytecode?
The name bytecode stems from instruction sets that have one-byte opcodes followed by optional parameters. Bytecode may often be either directly executed on a virtual machine (a p-code machine i.e., interpreter), or it may be further compiled into machine code for better performance.
Is .Java A source code?
In simple, we can say source code is a set of instructions/commands and statements which is written by a programmer by using a computer programming language like C, C++, Java, Python, Assembly language, etc. So the statements written in any programming language is termed as source code.
How is a bytecode converted to a machine code in Java?
Java programs mainly use bytecodes. When compiling a Java source code, the Java compiler converts that source code into a bytecode. Furthermore, this bytecode is executable by the Java Virtual Machine (JVM). The JVM converts the bytecode into machine code.
Which is executable by virtual machine or bytecode?
The bytecode is executable by a virtual machine. Moreover, the virtual machine converts the bytecode into machine code. Java programs mainly use bytecodes. When compiling a Java source code, the Java compiler converts that source code into a bytecode.
Which is platform independent byte code or machine code?
It is platform-independent as it is dependent on the virtual machine and the system having a virtual machine can be executed irrespective of the platform. It is not platform independent because the object code of one platform can not be run on the same Operating System.
How is source code converted to machine code?
All the source code need not be converted into byte code for execution by CPU. Some source code written by any specific high-level language is converted into byte code then byte code to object code for execution by CPU. All the source code must be converted into machine code before it is executed by the CPU.
