Java virtual machine

A Java Virtual Machine (JVM) is a piece of software that runs on your computer and lets you run programs written in Java. It works by taking the Java program you have written and transforming it into instructions that your computer can understand. The JVM is like a translator for your computer: it reads the Java code and translates it for your machine. This way, your computer is able to understand and execute the Java code without you having to write any special code for it.
