JDK, JRE, and JVM are all important components of the Java platform, but they serve different purposes. JVM stands for Java Virtual Machine, which is an abstract machine that runs Java bytecode. It provides a runtime environment in which Java programs can run, regardless of the underlying operating system and hardware. JVM interprets the Java bytecode and executes it on the underlying system. JRE stands for Java Runtime Environment, which includes the JVM, as well as libraries and other files necessary for running Java applications....
