Thanks, getting there.
I just get an error now :(
---------- javac ----------
IVA3ArraysVersion.java:509: cannot find symbol
symbol  : variable temps
location: class IVA3ArraysVersion
          display.setText(String.valueOf(temps[1]));     
                                               ^
1 error
Output completed (1 sec consumed) - Normal TerminationMaybe im setting up the array wrong.
This is all the code that i have done for the array.
     //Data
     int [] temps= new int [3];     
     temps[0] = 2;
     temps[1] = 4;       
     temps[2] = 2;
     // save array
     try
          fos = new FileOutputStream("temps.dat");
          oos = new ObjectOutputStream(fos);
          oos.writeObject(temps); 
          oos.flush();
          oos.close();
          catch(IOException ex)
          System.out.println("error writing: " + ex.getMessage());
     // load and print array
     try
          fis = new FileInputStream("temps.dat");
          ois = new ObjectInputStream(fis);
          int[] temps2 = (int [])ois.readObject();               
          ois.close();                    
          catch(IOException ex) // required
               System.out.println("error reading: " + ex.getMessage()); // for debugging
          catch(ClassNotFoundException ex) // required
               System.out.println("error reading: " + ex.getMessage()); // for debugging
          }My first proper attempt at using arrays.
Thanks
