What is JIT compiler? |
|
Answer» JIT STANDS for Just In Time. JIT compiler is a program which CONVERTS the Java BYTECODE into processor level instructions. The JIT compiler runs after the program has begun and COMPILES the bytecode while the program is running into a quicker and more local processor level directive set. After you've completed writing a Java program, the SOURCE code are compiled by the Java compiler into bytecode. Then the bytecode is converted into processor level instructions by the JIT compiler. Thus the JIT compiler acts as a second compiler. The JIT compiler runs simultaneously with the execution of the program. It compiles the bytecode into platform-specific executable code that is instantly executed. Once the code is re-compiled by the JIT compiler, it runs relatively quickly on the system. |
