Explain JVM in Java
Understand the Problem
The question is asking for an explanation of the Java Virtual Machine (JVM), which is a crucial component of the Java programming language that enables Java programs to run on any device that has the JVM installed, providing platform independence.
Answer
JVM is an interpreter between Java applications and hardware, providing a runtime environment and converting bytecode to machine code.
The Java Virtual Machine (JVM) acts as an interpreter between Java applications and the underlying hardware, providing a runtime environment to run Java programs on different platforms. It converts Java bytecode into machine code, allowing for platform independence.

The Java Virtual Machine (JVM) acts as an interpreter between Java applications and the underlying hardware, providing a runtime environment to run Java programs on different platforms. It converts Java bytecode into machine code, allowing for platform independence.
More Information
The JVM's ability to convert bytecode into platform-specific machine code is what gives Java its 'Write Once, Run Anywhere' capability. This means Java applications can be executed on any device that has a JVM, regardless of the underlying architecture.
Tips
A common mistake is confusing JVM with JRE or JDK. JVM is the runtime environment, JRE includes JVM plus libraries, and JDK is a development kit that includes JRE and developer tools.
