Description: 在Java开发平台，它将手机软件分为三个层次，最底层是OS(操作系统)层，负责内存读写、信号传输、指令处理等；最上层是手机的各种应用功能，如各种游戏、QQ聊天等；在两个层次之间是Java虚拟机，通过制定标准，负责Java语言与OS层之间的解释、编译。正是由于Java具有与硬件无关的特性，使得支持J2ME或BREW的软件，通过重新编译可以跨越芯片的硬件障碍，在不同手机上运行。-in Java development platform, cell phone software, which will be divided into three levels, the bottom is the OS (operating system) layer for memory read and write, signal transmission, processing instructions; At the top are the various mobile applications, such as games, chat QQ; In between the two levels is Java Virtual Machine, through the development of standards for the Java language and OS layer between the interpretation, translation. It is precisely because Java is hardware-independent, and makes support J2ME or BREW software, recompile across the chip hardware obstacles in running on different phones. Platform: |
