Definition
Java virtual machine (JVM) is a software engine that operates Java programs on any device, regardless of the operating system. It is used in many fields, including academic researchers and software developers.
How the Java Virtual Machine Works
- Write your computer program with the Java programming language (source code).
- Translate the source code into a format JVM can understand (bytecode) with a Java compiler.
- When you want to use your Java program, feed the JVM with the bytecode. The JVM reads and follows the bytecode instructions, allowing your application to operate on your computer.
- JVM makes your Java program compatible with different devices and operating systems.
Java Virtual Machine Use Cases
- JVM is used to build and execute applications and web services.
- Many businesses employ Java-based applications for data processing, customer management, and financial operations.
- JVM is used to develop Android applications with programming languages like Java and Kotlin.
- Research and academic institutions use JVM for research tools, simulation, and educational software.
