【摘要】 文中综述了具有代表性的Ｊａｖａ编译系统：以采用的虚拟机技术来划分的三代Ｊａｖａ编译系统，以及为特定平台的服务器端Ｊａｖａ程序设计的编译系统，对它们的结构和工作原理进行了阐述，并分析指出了它们各自的优缺点，进行了一些比较，为实现基于我国国产系统平台ＣＯＳＡ／ＣＯＳＩＸ上的Ｊａｖａ编译系统提供了很好的借鉴．更多还原

【Abstract】 The paper introduces the representative Java compiler systems:the three generations of Java compiler systems divided by different JVM techniques and a compiler system designed for platform specific server side Java applications. Their structures and theories are described and their respective advantages and disadvantages are pointed out. These compiler systems can be used for good reference for developing Java compiler systems based on the native system platform COSA/COSIX.更多还原
