import java.io.FileWriter;

public class Change {

public static void main(String[] args) throws Exception {
Change c = new Change();
c.utf8toLocaleCode();
}

public void utf8toLocaleCode() throws Exception {

BufferedReader br = new BufferedReader(new FileReader("D:/123.txt"));
BufferedWriter bw = new BufferedWriter(new FileWriter("D:/456.txt"));
String text = br.readLine();
while (text != null) {
String content = new String(text.getBytes("UTF-8"), "GBK");
System.out.println(content);
bw.write(content);
bw.newLine();
text = br.readLine();
}
br.close();
bw.close();
