JIT compiler(Just-In-Time compiler) A compiler that converts program source code into native machine code just before the program is run. In the case of Java, a JIT compiler converts Java's intermediate language (bytecode) into native machine code as needed. It tries to predict which instructions will be executed next so that it can compile the code in advance. Compiled code resides in memory until the application is closed. See Java compiler.

In most cases, executing JIT compiler
generated native code is more efficient than interpreting the equivalent bytecodes since an interpreter identifies and interprets a bytecode every time it is encountered during execution.
