In Java programming, a just-in-time (JIT) compiler is additionally given, as it has the capability to convert the bytecode of Java to the instruction, which can be feed straight to your processor. It starts running just once your program starts and compiles your source code on the fly (hence termed as just-in-time).
After writing the program the programmer runs the code in an appropriate language compiler specifying the name of the file that contains the source statements. When executing or running the program, the first task of the compiler is to parse all the language statement syntactically one after another and then build the .obj file and finally build the executable file (which is possible if the final code is correct).

JVM, i.e., Java Virtual Machine. JVM is the engine that drives the Java code. Mostly in other Programming Languages, compiler produce code for a particular system but Java compiler produce Bytecode for a Java Virtual Machine. When we compile a Java program, then bytecode is generated. Bytecode is the source code that can be used to run on any ...
