public class FileChange {
public static void copyFile(String fromFileName, String fileName)
throws Exception {
BufferedReader in = new BufferedReader(new InputStreamReader(
new FileInputStream(fromFileName)));
String str = null;
File file = new File(fileName);
PrintWriter out = new PrintWriter(file);
while ((str = in.readLine()) != null) {
out.println(str);
out.flush();
}
in.close();
out.close();
