Java Standard Edition (Java SE) is a widely-used programming platform that provides the core functionality for developing and running Java applications. It includes essential libraries, tools, and a runtime environment, allowing developers to create desktop applications, server-side applications, and more. Java SE is known for its portability, enabling programs to run on any device that has a compatible Java Virtual Machine (JVM). Java SE is part of the larger Java Platform, which also includes Java Enterprise Edition (Java EE) for enterprise applications and Java Micro Edition (Java ME) for mobile devices. The platform is maintained by Oracle Corporation, ensuring regular updates and enhancements to support modern programming needs.
