What is JIT ?..

Answer / umaira fathima

Since JRE version 1.2, Sun's JVM implementation has
included a JIT (just in time) compiler. Unlike the previous
interpreter that interpreted bytecode one instruction at a
time, the JIT compiler converts the bytecode for a program
into equivalent native machine code as the program is
loaded into the virtual machine.
This results in faster execution

Answer / tushar

JIT(just in time)compiler for the Java language allows
interpreted Java programs to be automatically compiled into
native machine language on the fly, for faster performance
of the program. Some JVMs include a JIT compiler.

Answer / rinky

Just in time(JIT) is a fast compiler.
Remember that when client system sends a request to server system,then the response is sent in two ways
1)static response(google page) using html
2)Dynamic response(ex:cricket score update information)using Applets
To send user(client system)response in the form of Webpage,applets program (in the form of bytecode) transferred from server to client system over the internet and executed using JIT(i.e converts bytecode to native code)
A webpage may contain number of applet programs to give different reponses(updated news,cricket score....)then to execute each program using JVM is time taking process.so,JIT is used to compile all applet programs at once to reduce response time.
