It is responsible for interpreting the bytecode, managing the memory, and providing the necessary environment for the execution of Java programs. The JVM is designed to be platform-independent, which means that the same bytecode can be executed on any system that has a JVM installed, regardless of the underlying hardware and operating system. JRE (Java Runtime Environment) is a software environment that provides the necessary components to run Java programs. It includes the JVM, libraries, and other files that are required to run Java applications. JRE is the minimum requirement for running any Java program. The JVM is an integral part o...
