What is it?
Java, or J2ME is a format for applications for mobile and PDAs. It provides software that can been added to mobile phones. It has been most widely used for mobile games, but many other applications such as maps, instant messengers, ip-based messaging, gps systems or phone book back-up systems have been developed.
As J2ME is widely available on mobile handsets, it offers the broadest compatibility in a highly fragmented market.
As advertising funded content increases, there will be greater demand to include this into Java applications. At the moment, most of these applications are games, however, recent studies have shown that this tends to focus on the 14-24 age range. In the older age demographic, PDA functions, such as diaries, maps or email are of the greatest interest. However, outside of the games market, there is a reluctance by many users outside of the early adopters to install applications on their mobile phones.
How does it work?
The Jave Platform, Micro Edition (J2ME) was developed by Sun Microsystems as a language and environment to run applications on mobile phones and PDAs. It’s programming language is Java, which is widely understood amongst programmers and developers. Although it is more complex to develop than simple Flash-based applications, it’s broad compatibility on mobile handsets makes it an attractive development proposition. As well as the phone-based functions J2ME can also be used to connect through the internet, bluetooth or infrared.
On the downside, as with other mobile content, the many different handsets on the market results in the need to develop many versions of each application. Whilst video and audio may be transcoded for handset optimization, J2ME applications will usually need to be developed specifically for different ranges of phones.
A few examples
There are many examples where J2ME has been used, from games to PDA style applications. Google, which is heavily involved with mobile apps provides its gmail and maps service through Java applications.
In France, Orange released a series of ad -funded games in 2007, sponsored by brands such as Coca-Cola and Saab.
Elsewhere, brands such as Nokia, McDonald’s, Diadora, Samsung, Adidas and Walt Disney have all sponsored J2ME applications.
