IntroductionThe previous articles have introduced the installation and configuration of Eclipse and its working environment, and completed various preparations. Therefore, this article will show you how to use the previously configured Eclipse development environment to create a j2_project and start a real journey of j2_development. Because this is the first j2-based program to be created, according to the practice of program development, it is natura

the "kill" Send call: Public static void main (string [] ARGs) throws exception { This expreditor means that when the expression is to call the send method of the messageconnection class, this call is replaced. Here I will replace it with a null string. So far, this class has been replaced. The B $1. class code after decompilation is changed to the following: Public void run () The line of send code does not exist, but there are two more lines of code: Textmessage textmessage1 = textmessage;Me

In j2s, the mobile media API (mmapi) is an optional package. It provides a standard API that can be used to express and obtain time-based media. Such as sound tracks and video clips. Mmapi is developed in JSR-135 in Java Community processes and is designed to be flexible and platform-independent, without making any assumptions about media formats, protocols, or features supported by different devices in the future. Mmapi is already used on mobile devices. For example, nokia3650 contains an imple

The J2EE platform has several important concepts, such as memory, CLDC, and MIDP. Beginners usually do not have a deep understanding of these concepts, and even have deviations. The purpose of this article is to describe the important concepts related to j2's.1. MemoryWe have been emphasizing that the memory size of mobile information devices is very small and should be cherished. However, we seldom know how these memories are classified. The followin

I am a newbie with a game project. I have some experiences and feel that I can share some things with you. Sorry for the mistake.Development Environment:Windows2000 + JBuilder X + semc_j2me_sdk_2_00004_betaI have never touched on this aspect, because a group of projects is about to start to learn j2_9. After reading the books for two days, I found that JDK is actually quite simple. There are several classes in total. However, if you want to consider the optimal optimization of resources and perf

Do you know how to add system calling APIs in KVM? Here we will describe different systems calling APIs and their implementations for different j2s devices, I believe this article will surely help you gain some benefits. How to add the system call API in KVM We all know that KVM does not support Native function calls. If you want to add some system-called APIs, you can only add them to KVM. At the same time, different j2's devices also have different

Hashtable instances have two parameters that affect their efficiency: capacity and load factor. The load factor is always 75% in CLDC implementation, and this value can be specified in other versions ). When the number of objects in Hashtable exceeds the load factor and a combination value of the current capacity, this may be obtained through the corresponding algorithm), the rehash method is called to Increase the capacity. Implementation principle of j2
