用 java 将文件的编码从GBK 转换成 UTF8

感谢博主laorer，原文地址：/article/1893142.html

private static void transferFile(String srcFileName, String destFileName) throws IOException

{

String line_separator = System.getProperty("line.separator");

FileInputStream fis = new FileInputStream(srcFileName);

StringBuffer content = new StringBuffer();

DataInputStream in = new DataInputStream(fis);

BufferedReader d = new BufferedReader(new InputStreamReader(in, "GBK"));// , "UTF-8"

String line = null;

while ((line = d.readLine()) != null)

content.append(line + line_separator);

d.close();

in.close();

fis.close();



Writer ow = new OutputStreamWriter(new FileOutputStream(destFileName), "utf-8");

ow.write(content.toString());

ow.close();

}
