Difference between JIT and JVM in Java? Answered The main difference between JIT and JVM is that JIT is part of JVM itself and its main function is to improve the performance of JVM by directly compiling some hot code (code that executes above a certain threshold) into native instruction. JIT stands for Just In time compilation and JVM stands for Java Virtual Machine. JVM is a virtual machine used in Java programming platforms to execute or run Java programs. The main advantage of JVM is that JVM  makes Java platform-independent by executing bytecodes. Java source code is compiled into class files, which contain bytecode.
