InputStreamReader&OutputStreamWriter是字节流转为字符流的桥梁，转换时（将字符编码成字节）可指定字符集。

写一个应用：
BufferedWriter bufw = new BufferedWrite(new OutputStreamWriter (new OutputStream("1.txt"),"UTF -8");

计算机底层操作的全是字节流：InputStreamReader将字节流转换成字符流，OutStreamWriter将字符流转换成字节流

说得很详细

BufferedReader bufr = new BufferedReader(new InputStreamReader(new InputStream("abc.java")));
BufferedWriter bufw = new BufferedWrite(new OutputStreamWriter (new OutputStream("abcd.java"),"UTF -8")
在网络编程时用到大量的io流，仔细体会用法很有帮助。PrintWriter流作用很大

恩，的确很方便
