As we know, Java is an Interpreted language as it’s generating byte code (intermediate) Code after compilation (javac). Then who and when will convert those intermediate codes to Machine understandable code? The answer is Interpreter and JIT compiler and Runtime, they will convert to machine code.
So we can say the JIT compiler helps in improving the performance of Java programs by compiling bytecode into native machine code at run time. On the other side, JVM is an engine that provides a run-time environment to run Java applications and it is part of JRE.
So in this video, we are going to explain some major differences between JIT and JVM.
