import java.io.DataOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;

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

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

        int v = 1001;
        data.writeInt(v);
        System.out.println("Successfully writes");
        data.close();

    }
}
