JIT means Just In Time compiler.The JIT used to compile java source file and generate class files.The execution engine means Java Virtual Machine(JVM) which executes the class files

A Java program is compiled into an intermediate language called bytecodes, and it can be executed on computers that have Java execution environment (engine). Overhead for interpreting bytecodes is huge.

JIT, Just-In-Time Compiler, allows much faster execution by compiling bytecodes into native machine code on the fly.

I would like to just add some more.  JIT is a feature available in java for faster execution of your java programs. Normally byte codes are converted to native code by execution engine in a step-by-step manner which is quite slow. With JIT enabled, a bunch of byte code is converted to native code in one go. This gives a performance boost.

jit is a part of execution engine ie once the class file is loaded it check the byte code 2 machine code then interpreter is checked for first time but if ur running 3,4 times the jit is checked bcaz the interpreter has already checked so jit is fast

JIT is a part of JVM. JVM consist of different part ByteCode Verifier, Constant Pool, Security Manager etc. JIT is also a part of JVM. It make the system or enviroment to understand the optimized set of instruction i.e the bytecode's on the fly

Java^(tm) is one of the mostdominant programming languages, and used for a wide range of applicationsincluding games and pervasive devices and mission-critical e-businessapplications. A Java program is compiled into an intermediate language calledbytecodes, and it can be downloaded through the network and executed on anycomputers that have Java execution environment. However, the overhead forinterpreting bytecodes is a serious bottleneck.

We have been researching and developing various techniques for the JavaJust-In-Time Compiler, which allows much faster execution by compilingbytecodes into native machine code on the fly. Our JIT compiler is used onalmost all Java platforms of IBM, ranging from network computers (NC) tomainframes.

JIT is compiler which is founded in jvm, & its isues to compiling bytecode into native machine code  amit saini
