What is JIT?

Short for just-in-time compiler, a code generator that converts Java bytecode into machine language instructions. Some Java Virtual Machines (VMs), including the VM in the Netscape Navigator browser, include a JIT in addition to a Java interpreter. Java programs compiled by a JIT generally run much faster than when the bytecode is executed by an interpreter.

When JVM compiles the class file he does not compile the full class file in one shot. Compilation is done on function basis or file basis. Advantage gained from this is that heavy parsing of original source code is avoided. Depending on need basis the compilation done. This type of compilation is termed as JIT or Just-In-Time compilation.
