I want to do Just-In-Time (JIT) compiler program so can you please provide me the details of the program?

In computing, Just-In-Time (JIT) compilation, is compilation done during execution of a program – at run time – rather than prior to execution.

The Just-In-Time (JIT) compiler is a component of the Java™ Runtime Environment that improves the performance of Java applications at run time.

Most often this consists of translation to machine code, which is then executed directly, but can also refer to translation to another format.

Java programs consists of classes, which contain platform-neutral bytecodes that can be interpreted by a JVM on many different computer architectures.

At run time, the JVM loads the class files, determines the semantics of each individual bytecode, and performs the appropriate computation.

The JIT compiler helps improve the performance of Java programs by compiling bytecodes into native machine code at run time.

The JIT compiler is enabled by default, and is activated when a Java method is called.

The JIT compiler compiles the bytecodes of that method into native machine code, compiling it "just in time" to run.

JIT compilation does require processor time and memory usage.

When the JVM first starts up, thousands of methods are called. Compiling all of these methods can significantly affect startup time, even if the program eventually achieves very good peak performance.

The JIT compiler can be disabled, in which case the entire Java program will be interpreted. Disabling the JIT compiler is not recommended except to diagnose or work around JIT compilation problems.
