What does "JVM (Java Virtual Machine)" mean in programming?
JVM (Java Virtual Machine) is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A runtime environment that executes Java bytecode. The JVM is what makes Java (and JVM languages like Kotlin, Scala, and Groovy) portable: compile once, run anywhere. It also handles garbage collection and JIT (Just-In-Time) compilation for performance.
Example
"The JVM's JIT compiler optimises hot code paths at runtime, which is why Java services often get faster after a warm-up period."
