ABSTRACT: The paper presents a new method of weather forecast presentation, which was developed as a project during the course of postgraduate study. So far, the use of mobile phones in the presentation of weather forecasts was limited and noninteractive. This application provides an interactive access to meteorological products in Croatia. It has been developed in the MicroJava programming language and successfully tested in an emulator and on real mobile devices. The rapid development of mobile technologies will allow for intensive application of such products. Key words: Java, weather forecast, MIDlet, J2ME, MicroJava, mobile device, wireless, GPRS
1. Introduction This paper describes a new method of weather forecast presentation based on modern mobile communication technologies – at the moment the fastest-growing industry in the world. Recent studies show that every fifth person in the world owns a mobile device, and in Croatia more than 80 percent of households have at least one; at the same time, only 37 percent have a personal computer (GFK, 2003). 2. Technology In June 1999, Sun Microsystems announced a new edition of the Java 2 platform: the Java 2 Micro Edition -J2ME (Muchow, 2002). The purpose of the Micro Edition is to enable Java applications to run on computing devices with limited computer power, memory and display, such as mobile phones, PDAs, pagers, etc. It is based on the popular Java programming language, and the application is called MIDlet.
MIDlet is an abbreviation composed of two words: MID for Mobile Information Device, and “let”...
