JAVA Filing related

I am writing some 32 bit integer data in matlab using statements such
as:

f=fopen('temp','w');
a=int32(23);
fprintf(f,'%d',a);
fclose(f);

and trying to read in in JAVA using:
 public static void main(String[] args) {
        // TODO code application logic here

    File file = new File("C:\\JAVA\\temp");
    FileInputStream fis = null;
    BufferedInputStream bis = null;
    DataInputStream dis = null;

    try {
      fis = new FileInputStream(file);

      // Here BufferedInputStream is added for fast reading.
      bis = new BufferedInputStream(fis);
      dis = new DataInputStream(bis);
 int a;
      a = dis.readInt();
      System.out.print(a);
      // dispose all the resources after using them.
      fis.close();
      bis.close();
      dis.close();

    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }//end catch2
    }//end main

======================

Now logically, reading a 32 bit integer using this command should work
fine, but I am getting out of range values, like, if i am just reading
in integer valued 32, it would rather print 8924558 or something like
that, garbage values. I have tried using read other reading methods as
well such as readByte, readShort, read etc but only thing that works
is readln, which I don't want. It brings in whole line of data, which
i don't want. Rather, I need individual integers to be read, perhaps
delimited by tabs or new lines
