J2ME 是SUN 公司针对嵌入式、消费类 电子产品推出的开发平台，与J2SE 和J2EE 共同组成Java 技术的三个重要的分支。J2ME 实际 上是一系列规范的集合，由JCP 组织制定相关的Java Specification Request（JSR）并发布，各 个厂商会按照规范在自己的产品上进行实现，但是必须要通过TCK 测试，这样确保兼容性。比 如MIDP2.0 规范就是在JSR118 中制定的。可能接触过J2ME 的开发者会觉得说J2ME 是一系列 的规范不准确吧。因为我们在开发中用到了很多例如CLDC（Connected Limited Devices Configuration）和MIDP（Mobile Information Devices Profile）等内容。-J2ME is targeted at embedded SUN companies, and consumer electronics products launched development platform, J2SE and J2EE and Java technologies together constitute the three major branches. J2ME is actually a collection of a series of norms, by the JCP-related organizations to develop Java Specification Request (JSR) and publish various vendors will be in accordance with the norms in their own products to realize, but must pass TCK test, so to ensure compatibility. For example, MIDP2.0 specification is developed in JSR118. May come into contact with J2ME developers will find that J2ME is a series of standards are not accurate now. Be
