Do i need to have an StaffList Lenght to String ?

to get this Working as i cant figure out how to get this working

i dont have an StaffList lengthToString() method..

i was trying all different types of ways, i forgot to cut that code out

out.write(StaffList.lengthtoString());

OK thank you, I was Kinda Guessing it was calling the Withdraw and Deposit every time i ran it,

SO i move the Withdraw and Deposit

into the Else. and its working fine,, it was hitting me in the face for about 10 mins..

OK i got the Array to save to a .DAT file,

No Errors or anything,

But when i run it for the first time its giving me this Output:


0:1200.0
Expected: 1200
1:1500.0
Expected: 1500
2:4000.0
Expected: 4000
3:-3000.0
Expected: 3000

Thats all good but when i try and Read it back in,

its giving me
0:1400.0
Expected: 1200
1:1000.0
Expected: 1500
2:5000.0
Expected: 4000
3:-4000.0
Expected: 3000

And if run it again
0:1600.0
Expected: 1200
1:500.0
Expected: 1500
2:6000.0
Expected: 4000
3:-11000.0
Expected: 3000

Is this Normal ?

ok,

i added

public class Bank implements Serializable
{



/**
*
*/
private static final long serialVersionUID = 1L;




getting

Exception in thread "main" java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: Bank

Seems to be Something wrong with the Write Object..
