java 语言默认的编码方式是unicode ，而我们中国人通常使用的文件和数据库都是基于 gb2312 或者 big5 等方式编码的，怎样才能够恰当地选择汉字编码方式并正确地处理汉字的编码呢？本文将从汉字编码的常识入手，结合 java 编程实例，分析以上两个问题并提出解决它们的方案：
1．在jsp程序中加入一条语句：
2．在url请示字符串的编码问题。

the java runtime searches for the startup class, and other classes used, in three sets of locations: the bootstrap class path, the installed extensions, and the user class path.
non-option arguments after the class name or jar file name are passed to the main function.
options
the launcher has a set of standard options that are supported on the current runtime environment and will be supported in future releases. in addition, the current implementations of the virtual machines support a set of non-standard opt...
