2.1 Why Java?Before Java was called Java, it was Oaka programming language designed for TV set-top boxes and other devices (see "Resources"). Considering its deep roots in devices, there is no surprise that many philosophies and designs behind the Java technology are perfectly suited for mobile applications. The advantages of the Java technology are as follows.Cross platform: This is very important in the diversified mobile device market. In a heterogeneous enterprise environment, the ability to develop and maintain a single client for all devices results in huge savings.Robust: Since Java applications are completely managed, the bytecode is verified before execution, and memory leaks are reclaimed by garbage collectors. Even if a Java application does crash, it is contained within the virtual machine. It will not affect other sensitive applications or data on the device.Secure: The Java runtime provides advanced security features through a domain-based security manager and standard security APIs.Object oriented: The Java language is a well-designed, object-oriented language with vast library support. There is a vast pool of existing Java developers.Wide adoption at the back end: It is relatively easy to make Java clients work with Java application servers and messaging servers. Due to the wide adoption of Java 2 Enterprise Edition (J2EE) on the server side, mobile Java is the leading candidate for enterprise frontend applications. However, technical merits are not the only factors that determine the success of a technology. The business values are just as important. In particular, the vendor's ability to address the concerns of the developer and user community is key to the technology's adoption. Now, let's have a look at how the Java community influences the evolution of the technology. |
