Java Virtual Machine (JVM) is an abstract computing machine that provides an environment in which Java programs can be executed. The JVM is a key component of the Java platform and is responsible for interpreting the compiled Java code and providing a runtime environment for the code to run.
When a Java program is compiled, it is translated into bytecode, which is a platform-independent code that can be executed on any machine that has a JVM installed. The JVM then reads the bytecode and translates it into machine code that can be executed on the host operating system.
The JVM is responsible for many important functions, including memory management, garbage collection, and security. It also provides a wide range of libraries and tools for developers to use in their Java programs.
One of the main advantages of using the JVM is that it provides platform independence, meaning that Java programs can be written once and run on any machine that has a compatible JVM installed. This makes Java a popular choice for developing applications that need to run on multiple platforms.
