Difference Between Bytecode and Machine Code

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 the difference between machine code and object code?

Object code is a portion of machine code that has not yet been linked into a complete program. ... Whereas machine code is binary code that can be executed directly by the CPU, object code has the jumps partially parameterized so that a linker can fill them in.

Is bytecode the same as assembly code?

Bytecode is similar to assembly language in that it is not a high-level language, but it is still somewhat readable, unlike machine language. ... The primary difference between the two is that bytecode is generated for a virtual machine (software), while assembly language is created for a CPU (hardware).

Which converts bytecode to machine code in Java?

Java Virtual Machine (JVM) is a engine that provides runtime environment to drive the Java Code or applications. It converts Java bytecode into machines language. JVM is a part of Java Run Environment (JRE). In other programming languages, the compiler produces machine code for a particular system.

What is computer machine code?

In computer programming, machine code, consisting of machine language instructions, is a low-level programming language used to directly control a computer's central processing unit (CPU).

Is bytecode a machine code?

The main difference between the machine code and the bytecode is that the machine code is a set of instructions in machine language or binary which can be directly executed by the CPU. While the bytecode is a non-runnable code generated by compiling a source code that relies on an interpreter to get executed.

What is object code example?

Object code is the language that a central processing unit can understand after it has been translated by the compiler from the programming source code. An example of object code is ELF (Executable and Linking Format). ... See executable code, linker, machine language and object-oriented programming.

Why is it 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.

Why do we need bytecode?

If you have to compile the code for a given processor architecture you would have speed but not portability. With the bytecode, you compile the code (into bytecode) for a common machine that will execute it (the JVM) it is a compromise between speed and portability.

What is object code and executable code?

Object code is a sequence of statements in binary that is generated after compiling the source program. In contrast, an executable code is a file or a program that indicates tasks according to encoded instructions which are directly executed by the CPU.

What converts code to bytecode?

The Java compiler (javac) converts the source code into bytecode. Bytecode is a kind of average machine language. This bytecode file (. class file) can be run on any operating system by using the Java interpreter (java) for that platform.

Is JVM a compiler?

JVM have both compiler and interpreter. Because the compiler compiles the code and generates bytecode. After that the interpreter converts bytecode to machine understandable code.

Which is invalid identifier with the main method?

Which of the below is invalid identifier with the main method? Explanation: main method cannot be private as it is invoked by external method. Other identifier are valid with main method.
