JVM stands for Java Virtual Machine, which doesn't have any physical directories created in java installation. JRE stands for Java Runtime Environment, which creates the directory under Java installation path and also present in JDK. JDK stands for Java Development Kit, which creates the directory in Java installation path and also it has it's own JRE. Since we have already learn that Java is platform independent means if we have implemented any of the java class in one environment, it will be executed in any other environment and provides the same output. But, JVM, JRE and JDK all are platform dependent . So that, for windows, linux, unix, mac, solaris..etc has it's own JVM, JRE and JDK. One will be not compatible with other environments. While installing the Java, we might come to know a bit about JRE and JDK. But, JVM is the other...
