2.2 The Java Community Process

The concept of open interfaces is core to the Java technology. It works as follows: For a given computing task, a set of standard APIs is defined by a standards committee. Individual vendors then provide competing libraries that implement those APIs. The application code using the API is completely decoupled from the specific implementation provider. That approach minimizes the developer's learning cost and improves code portability. Yet, it also protects the freedom of choosing vendors. The Java Community Process (JCP) is an effort to develop standard Java API specifications.

JCP Executive Committees (ECs, see Table 2.1) consist of industry leading companies. Anyone in the general public can submit a new Java Specification Request (JSR) for a new API. The appropriate EC decides whether to accept this new JSR. Once approved, the JSR lead can recruit more companies or individuals to develop the API specification together. Every specification goes through multiple stages of community and public reviews before it becomes an official Java standard.

The JCP ensures that all interested parties can express their concerns. As a result, the final APIs are supported by industry consensus. All standard mobile Java APIs are developed democratically through the JCP.

Now, let's look at the most trends in the Java world and how they relate to mobility.
