Turn from: http://developer.51cto.com/art/201009/228387.htm The JAVA2 platform includes the Standard Edition (J2SE), Enterprise (Java) and miniature (J2ME) Three versions, here to describe the three versions of the difference and contact, I hope to help you learn. This article gives you a brief introduction to J2SE, the difference between Java EE and J2ME, most programming languages have a preselected cl

J2ME Novice, did a game project, some experience, feel that some things can still be taken out and share. Excuse me if I'm wrong. Development environment: Windows2000+jbuilder X+semc_j2me_sdk_2_1_4_beta Never contacted this aspect, because the Group a project to start to learn J2ME, read two days of books, found that the JDK is still very simple. There are a total of those classes. Only if you want to co

Practical Teaching of JAVA-J2ME mobile development Java 2 Micro Edition is a part of Java 2 and is also known as j2se and J2EE. It is a highly optimized Java operating environment and is applied to a large number of consumer electronic devices, such as cell phones, visual phones, digital set-top boxes, and car-oriented systems, it is also widely used by mobile communication devices, such as mobile phones, two-way pagers, smart cards, perso

Here I first thank you to the previous article J2ME Mobile 3D Introductory Tutorial series of the support of one of the articles, it is also with the support of everyone, I decided to take my mobile3d learning process to share with you, I hope we can together to discuss Mobile3d. 　　 In the last tutorial I gave you a specific introduction, in the Moble3d through the timely operation of the creation of 3D graphics, and the import of models from the *.

-------------General class Problems-------------- 1 j2me table method using trigonometric functions CLDC and MIDP do not provide trigonometric functions, and there is no floating-point number in the CLDC1.0, so our choice is to check the table. Use the sin and Cos tables with 8-bit fixed-point numbers. The following is the code in the WTK demo, which provides only a limited number of angles, which are used to refine the angle value as needed. //Si

This article mainly elaborated the question is, in J2ME development the event transmission exactly is what mechanism. This paper mainly focuses on the analysis and research of the serial of canvas event transmission, and proves it through an example and concludes at the end.By referencing Java Doc We can know that the event transmission in J2ME is serialized, so what is serialization? Java Doc says the foll

Gamecanvas is one of the most important elements of MIDP2.0, improve the convenience of J2ME game development, compared to MIDP1.0, reduce the difficulty and cost of J2ME game development, this article specifically detailed the Gamecanvas game canvas of the relevant content, the Gamecanvas has a general analysis. The main methods, methods and methods in Gamecanvas are summarized as follows: 1, the method

Using fonts In J2ME mobile programming, you can use the Font class--font in the low-level user interface to achieve better performance, then how to use the Font class? First of all, due to the limitations of mobile devices, the type of font supported in mobile phones is limited, so the font class object can only be constructed using the default font supported by the mobile phone in J2ME. The following are

In the process of generating random numbers, useful comparisons, such as artificial intelligence, and so on, here for the J2ME in the production of random number of operations to do a simple collation, I hope that we can help. Unlike J2ME and J2SE, you cannot use the random of the math class to generate random numbers, only using the random class of the Java.util package to generate random numbers. First,

The way of expression of time There are two ways of expressing time in J2ME: 1, with the GMT1970 year January 1 Midnight 12 o'clock and now the difference between the number of milliseconds to represent, this approach is suitable to compare the difference between two times. 2, in the form of objects to express Second, the related class of time processing Time processing involves three classes in J2ME:
