Question

What are just-in-time compilers?

a.

Programs that read a program's bytecode executable and execute it in a virtual environment implemented in software.

b.

Programs that translate high-level bytecode instructions into dozens of instructions on the physical CPU.

c.

Programs that take snippets of program bytecode at runtime and compile them into the native processor's machine language before running them.

d.

Programs that execute bytecode directly on the host processor.

Answer: (c).Programs that take snippets of program bytecode at runtime and compile them into the native processor's machine language before running them. Explanation:Just-in-time compilers (JITs) are an alternative approach for running bytecode programs without the performance penalty associated with interpreters. The idea is to take snippets of program bytecode at runtime and compile them into the native processor's machine language before running them. These snippets are then executed natively on the host's CPU, which results in faster performance compared to running the bytecode through an interpreter.
