代码说明：

Java内核是unicode的，就连class文件也是，但是很多媒体，包括文件/流的保存方式是使用字节流的。因此Java要对这些字节流经行转化。char是unicode的，而byte是字节。Java中byte/char互转的函数在sun.io的包中间有。其中ByteToCharConverter类是中调度，可以用来告诉你，你用的convertor。其中两个很常用的静态函数是-Java kernel is unicode,as well as class files.However,most multimedias use stream bytes,including the way of their storage.So java ought to convert these stream bytes.char is unicode,while byte is byte.byte/char convertion function is in sun.io.class ByteToCharConverter could tell you which convertor you are using.two usual static functions are
