Brief Introduction
At any time, we suddenly feel that everyone around us has a mobile phone. Using mobile phones to communicate with others has become a part of our lives. People in some of the most advanced countries in northern Europe can use their mobile phones to buy the goods sold by vending machines, and they can use mobile phones as a tool of authentication when engaging in business (m-commence) transactions. In Japan, many of the additional functions of mobile phones are part of the youth culture. The coming 3G, wireless broadband dream brings people to the future of wireless communication expectations.
Then, some manufacturers began marketing their own PDA, as if no PDA in hand, it is not like modern people. A wide variety of PDA flooded the market, best-selling and not selling, people are dazzled by confusion. There was a big problem--it was a lot of trouble to have our phones and PDAs at the same time--even if they were thin and short. Wouldn't it be more convenient to have a cell phone with a PDA? Then hear the consumer voice of the manufacturers, began to launch a mobile phone and PDA integrated products, from NOKIA 9000, Motorola A6188 (Taiji), to the recent launch of the Ericsson R380, NOKIA 9210, are mobile phone and PDA combination of examples, Although the price of the relationship, but these products are still many people dream of high order products.
Despite the combination of PDA and cell phone products appear, we still feel that there is insufficient, I think you must have found that the application is inadequate, although the phone and PDA combined, but these products on the PDA function seems to be dead. We can write the applications on these platforms on PalmOS, Windows CE, EPOC, and so on PDA, but never have the opportunity to download our written program to these mobile phones (even if some mobile PDA is also using EPOC, such as Ericsson R380).
I believe that the manufacturers also hear the voices of our engineers who like to write programs everywhere, so starting from the end of 2000, there will be a lot of support for Java mobile phone will soon be launched, of course, these manufacturers also provide a mobile phone development Program SDK, we can finally write small programs on the phone to amuse themselves! It's a dream I've been waiting for so long.
Mobile phone platform diversity and complexity, and PDA can be said to be even more, so we can know-ha! It's time for Java to come in handy. We all know the Java program that executes on the browser is called the applet, the Java program that executes on the PalmOS is called Spotlet, but the application that executes on the handset we call MIDlet, believe to everybody is a strange noun, This is also the main character to be introduced in this article.
