java文件读写编码方式设置

读

Java代码

FileInputStream fr = new FileInputStream(path);

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

BufferedReader br=new BufferedReader(is);

br.readLine();

写

Java代码

FileOutputStream stream;// provides file access

OutputStreamWriter writer;// writes to the file

stream = new FileOutputStream("test.xml");

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

writer.write("This is a test");

writer.flush();

wirter.close();

在用java写文件的时候我们往往利用这种方式：

BufferedWriter output = new BufferedWriter(new FileWriter(new File("filepath")));

但是利用这种情况写的文件编码格式默认是当前操作系统的编码格式，

如果想设置为您所需要的格式现在可以利用这种方法：

OutputStreamWriter output = new OutputStreamWriter(new FileOutputStream("filepath"),"UTF-8");这样就可以设置为你所需要的格式了，具体的原理稍后补上。
