Mobile is also in many ways responsible for the proliferation of Java and its uses in the day-to-day life of a common man, world over.
Java for job aspirants
Java on a mobile has not only opened up a window of limitless opportunities for the users of devices such as smartphones running on various platforms but also become a medium of economic uplift of job aspirants. There has been a corresponding rise in demand for Java professionals along with increasing demand for devices with newer more attractive applications.
There are popular social media groups that constantly ensure that Java keeps pace with changing technological landscape. Such is the overwhelming popularity of Java that recently when Oracle reportedly decided to put in the backburner the development of Java Enterprise Edition (EE) (a popular server-side platform for developing and running Java-based apps), Java EE Guardians group forced the company to reinstall the project through a signature campaign.

Boreland JBuilder is a popular Java IDE (Integrated Development Environment) comprising of Personal, Standard Edition (SE) and Enterprise editions (EE). JBuilder 7 Enterprise offers tools that enable Java application namely J2EE design, development, deployment and testing.
Learn software engineering
Despite its seeming easy availability, Java mobile application development comprises of a complex engineering process. It includes numerous facets of software engineering. Integrated Development Environment or IDE provides tool of automation of various tasks and facilities that help programmers develop software but it calls for understanding and learning of various features of the software engineering.
