What are Java Technologies?

Java technologies cover the ecosystem of products that support the Java development environment and its runtime world. Java is a secure object-oriented programming language that is readily portable and used for everything from developing mission-critical applications and rich web applications to running millions of mobile and medical devices, computers, and gaming consoles. It is described as a write once, run anywhere (WORA) language.

Java technologies are deployed by enterprise organizations to support their Java IT infrastructure and application development activities. They include three major components: Java Development Kits, Java Runtime Environments, and Java Virtual Machines.

Java Development Kits (JDKs) support the coding of Java applications and applets. They can run on Windows, Linux, Solaris, and macOS and include compilers and debuggers. They include JREs, which are required to run Java programs.

Java Runtime Environments (JREs) include the necessary resources to run Java programs, including class libraries, class loaders, and JVMs.

Java Virtual Machines (JVMs) execute Java programs. JVMs provide platform independence when running Java code. They include a just-in-time (JIT) compiler for faster execution performance.

Platforms and Variants

The OpenJDK project is an open-source implementation of Java that supports many commercial and open-source products. Oracle also maintains and offers the following specialized builds of Java:

Java SE (Standard Edition) is used to develop APIs, desktop, web, mobile, iOS, and Android applications.

Java EE (Enterprise Edition) is used to build distributed computing, web services, and large-scale applications such as those used by finance, eCommerce, and accounting companies.

Java ME (Micro Edition) is used to run mobile phones, IoT devices, and other devices.

Java JMS (Java Management Service) monitors, manages, and reports on Java performance in the cloud or on-premises.

Java Card Technology enables smart cards and chips to host multiple Java applications.

Java Technologies Comparison

Consider the following when purchasing Java technologies.

Oracle vs. Commercial Open-Source vs. Open-Source Products

Use Case: To ensure high performance, stability, and security for mission-critical commercial use, either Oracle or commercial open-source platforms such as Azul would be recommended.

Cost: Oracle and commercial open-source Java platforms charge licensing fees for their products. Free open-source versions (OpenJDK) are available.

Features: Oracle and other commercial Java products offer more features than free open-source products.

Support: Both Oracle and commercial open-source Java vendors provide tech support. Free open-source Java users rely on the open-source community for any support needs.

Other Considerations

Scope: Java Runtime Environments (JREs) can be stand-alone installations deployed for executing applications without requiring a JDK.

Platform Migration: Migrating from Oracle to an open-source platform can help prevent an organization from being overly dependent on one tech vendor. Commercial open-source vendors will commonly provide migration support services.

Pricing Information

Pricing for commercial open-source products can vary greatly based on the number of core servers or the number of desktops. Final costs can range from under $1,000 to over $400,000 per year depending on the product, features, and deployment scale. Discounts are offered for large-scale installations; for enterprise organizations that can run into hundreds of thousands of dollars. There are cost-free open-source Java technologies.
