Java Platforms/Editions

 

Java Platforms / Editions

Java platforms refer to the different editions or versions of the Java programming language and associated tools Oracle Corporation provides. Each platform edition is designed for specific types of development and deployment environments. Here are the main Java platforms/editions:

1. Java SE (Standard Edition):

   • Java SE is the core Java platform designed for general-purpose programming.
   • It provides the foundation for developing and running Java applications on desktops, servers, and other devices.
   • Java SE includes the Java Development Kit (JDK), which includes tools for developing, debugging, and monitoring Java applications.
   • It also includes the Java Runtime Environment (JRE), which is required for running Java applications on end-user devices.

2. Java EE (Enterprise Edition):

   • Java EE is a set of specifications and APIs for building enterprise-level applications.
   • It provides a runtime environment and APIs for developing distributed, multitiered, and scalable applications.
   • Java EE includes technologies for web development, such as servlets, Java Server Pages (JSP), and Java Server Faces (JSF), as well as for enterprise services like messaging, transactions, and security.
   • Java EE application servers, such as Apache Tom EE, IBM WebSphere, and Oracle WebLogic, implement the Java EE specifications.

3. Java ME (Micro Edition):

   • Java ME is a platform for developing applications for resource-constrained devices, such as mobile phones, embedded devices, and IoT (Internet of Things) devices.
   • It provides a subset of the Java SE platform optimized for devices with limited memory, processing power, and display capabilities.
   • Java ME includes profiles and configurations tailored for specific device categories and requirements.

4. Java Card:

   • Java Card is a subset of Java ME designed specifically for smart cards and other secure, resource-constrained devices.
   • It provides a secure execution environment for Java applications on devices with very limited resources and stringent security requirements.
