i know that the JDK consists of all java packages .But what does the JRE consist of apart from java.exe ? I could understand the necessities of things in 'bin' folder in the JRE but what about the 'lib' folder ?
推荐答案
有看看这个 JDK和JRE文件结构来自Sun的JDK文档的文档。
Have a look at this JDK and JRE File Structure document from Sun's JDK documentation.
它具体说明了以下 lib
目录:
It specifically says the following about the lib
directory:
Java运行时环境使用的代码库,属性设置和资源文件。例如:
Code libraries, property settings, and resource files used by the Java runtime environment. For example:
- rt.jar - 引导类(构成Java平台核心API的RunTime类)。
- charsets.jar - 字符转换类。
除了ext子目录(如下所述)之外,还有这里没有描述几个额外的资源子目录。
Aside from the ext subdirectory (described below) there are several additional resource subdirectories not described here.
