java读文件和写文件编码方式的控制

在java中常常遇到文件读写的问题，有时候需呀控制读写文件的编码格式

方法如下：

读文件
FileInputStream fr = new FileInputStream(path);

InputStreamReader is = new InputStreamReader(fr,"UTF-8");

BufferedReader br=new BufferedReader(is);
写文件
FileOutputStream stream;// provides file access

OutputStreamWriter writer;// writes to the file

stream = new FileOutputStream(filename);

writer = new OutputStreamWriter(stream,"UTF-8");
