    The JIT compiler compiles the bytecodes of that method into native machine code, compiling it "just in time" to run. When a method has been compiled, the JVM calls the compiled code of that method directly instead of interpreting it.

    JIT is the Just-In-Time compiler in Java. It compiles the byte code into machine code, running just in time.

    Just in time (JIT) is a production strategy that strives to improve a business' return on investment by reducing in-process inventory and associated carrying costs. Just in time is a type of operations management approach which originated in Japan in the 1950s.

    -There are strong cultural aspects associated with the emergence of JIT in Japan. The Japanese work ethic involves the following concepts.
    -Workers are highly motivated to seek constant improvement upon that which already exists. Although high standards are currently being met, there exist even higher standards to achieve.
    -Companies focus on group effort which involves the combining of talents and sharing knowledge, problem-solving skills, ideas and the achievement of a common goal.
    -Work itself takes precedence over leisure. It is not unusual for a Japanese employee to work 14-hour days.
    -Employees tend to remain with one company throughout the course of their career span. This allows the opportunity for them to hone their skills and abilities at a constant rate while offering numerous benefits to the company.

    Seems it is oldone, but maybe this information will be helpful for someone who have found this page on websearch.
    Most developers heard about JIT compilers and how they can make slow interpreted languages run at a speed, comparable to native code. However, not many people understand how exactly this JIT thing works, and even less people could write their own compilers.
    For clearly understanding please check:
    the Wikipedia page on JIT
    Interesting blog https://darksi.de/4.how-to-start-jitting/
