输出流
有哪些构造方法可以在参数上设置编码格式
PrintStream(File file, String csn)PrintStream(String fileName, String csn)PrintWriter(File file, String csn)-
PrintWriter(String fileName, String csn)(注：PrintWriter类的构造方法可以接收OutputStream) -
OutputStreamWriter(OutputStream out, Charset cs)(注：An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are encoded into bytes using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.可知OutputStreamWriter发挥了桥梁的作用）
