Save game and load game??

Question

i wrote a simple word base Rpg game, try to save some data and positions to a file, but dont know why it just allows me to save integer from 0-255?? why?? can anyone help? the code is following,
public void Save () throws IOException {
          x = in.readInt();
          y = in.readInt();
          FileOutputStream out = new FileOutputStream("save1");
          ObjectOutputStream o = new ObjectOutputStream(out);
          o.write(x);
          o.write(y);
          o.flush();
public Load () throws IOException {
          FileInputStream in = new FileInputStream("save1");
          ObjectInputStream i = new ObjectInputStream(in);
          int a = (int)i.read();
          int b = (int)i.read();

well...dont know what's the problem between you two.......but here is the codes.
import java.io.*;
public class Save {
          static int x = 0;
          static int y = 0;
     public void saveTo() throws IOException{
          DataOutputStream out = new DataOutputStream(new FileOutputStream("Tesing"));
          DataOutputStream s = new DataOutputStream(out);
          s.writeInt(x);
          s.writeInt(y);
     public static void main(String[] args) throws IOException{
          BufferedReader console = new BufferedReader(
               new InputStreamReader(System.in));
          System.out.print("How old are you?");
          String input = console.readLine();
          x = Integer.parseInt(input);
          System.out.print("How tall are you?");
          String input2 = console.readLine();
          y = Integer.parseInt(input2);
          Save sa = new Save();
          sa.saveTo();
import java.io.*;
public class Load {
     public static void main(String[] args) throws IOException{
          DataInputStream in = new DataInputStream(new FileInputStream("Tesing"));
          DataInputStream i = new DataInputStream(in);
          int a = i.readInt();
          int b = i.readInt();
          System.out.println(a + "\n" + b);
}
