A certain set of several software products and specifications is known as Java. Developed by the Sun Microsystems (now a part of Oracle Corporation), Java provides a system application development software that can be deployed over various cross platform computing environment. The software product is utilized on a number of computing platforms from mobiles to embedded devices, to the enterprise servers and supercomputers. The Java applets are used to provide security when browsing the internet.
Writing of the language produces code as Java bytecode. Though there are compilers for languages like JavaScript, Python, Ruby and Ada, the new language is designed to run locally on the Java Virtual Machine (JVM) named Groovy, Clojure, and Scala. The syntax borrows heavily from C++ and C. With a simple memory model, all objects are heaped and the variable object types are referred. The memory management is processed by JVM’s automated garbage collection.
The language of Java has undergone many changes since the launch of Java Development Kit 1.0 in January 23, 1996. After the J2SE 1.4, the Java Community Process (JVM) primarily governed this language.
The Java Platform, Micro Edition
The Java ME language is a platform devised for embedded systems, like devices such as a mobile phone to industrial objects to set top boxes. Designed by the Sun Microsystems, the platform was the replacement of Personal Java, a similar technology. Developed under the JCR as the JSR 68, as per December 22, 2006 the J2ME is licensed under the GNU General Public License.
Distinction between J2ME and Android
Both Android and J2ME are used to create mobile applications. The following are some of the key differences between the J2ME Applications and Android Software Applications:
The Android mobile devices come with more functionality than J2ME. Equipped with camera and GPS, the Android can be configured to incarcerate data using customized code of third parties. This enables integration of novel data. J2ME can perform similar multimedia playback and GPS collection, but it makes the phone more expensive. GPS and J2ME need a S60 operating system which is more complex.
The Android mobiles are built integrating user interface allowing easier working interface and enabling easier navigation. Much more intuitive than J2ME, the problem lies in mistaken entries or accidental exits from the application. On the other hand, J2ME interface is limited but streamlined and can take over entire functionality of the device.
The display screen of the Android is much bigger for easy accessing. The J2ME apps are optimized for better visibility albeit in a much smaller screen. This makes sharing of videos and images difficult. However, in Android, the viewing angles can be resistive.
Android with low-technical capacities have been using ODK in the past but many components were difficult to adopt. The widgets were more visible and easier to use. J2ME supports “sense” mode. This is designed for users with low technical capacity. Familiar with those who use the S40 Smartphone are often frustrated with the inefficiency of sense interface.
The Android apps require fewer configurations and have automatic updates. With the highest turnover this year, the Android was the preferential choice for most users. J2ME requires manual configurations that are deleted once the battery runs out. Although, the phones have improved local support, but there has always been complaints of fraudulences.
The Android already have specific external features deployed in the device that the user can take advantage of. The J2ME is inconspicuous, though there is an extensive range that is available in the market.
