public class DataOutputStreamwriteChars {
    public static void main(String[] args) throws IOException {

        FileOutputStream file = 
               new FileOutputStream("D:\\hello.txt");
        DataOutputStream data = new DataOutputStream(file);

        String s = "hello";
        data.writeChars(s);
