• What is JIT compiler and interpreter in Java?

  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. When a method has been compiled, the JVM calls the compiled code of that method directly instead of interpreting it.

• Is JIT a compiler or interpreter?

  For example, in the Java programming language and environment, a just-in-time (JIT) compiler turns Java bytecode -- a program that contains instructions that must be interpreted -- into instructions that can be sent directly to the processor.

• What is the difference between JIT and interpreter in Java?

  Interpreter: Reads your source code or some intermediate representation (bytecode) of it, and executes it directly. JIT compiler: Reads your source code, or more typically some intermediate representation (bytecode) of it, compiles that on the fly and executes native code.
• JIT compiles bytecode to native machine code to optimise efficiency. JVM interprets the same sequence of bytecode repeatedly and incurs a longer execution time. The hardware executes the native code of repeated method calls. JIT compiler is a part of the JVM.
