Jump to PostYou provide no information about testDate and Acount
Jump to PostThe exception you got is not about the file but in fact it's an ArrayIndexOutOfBoundsException; but the message you show is your's.
Try to depect the incremetation of th i value.
Hope it helps.
Jump to PostYou increse the value of i without incresing the size of the account array.
That is the error.

You increse the value of i without incresing the size of the account array.
That is the error.
I thought by increasing "i" i was increasing the size of the array , if its not too much trouble could u correct the error and copy and past it and show me please ?

Add those instructions after increasing i and let me now!
Account [] newaccount = new Account [i] ;
System.arraycopy(account, 0, newaccount, 0, account.length);
account=newaccount;

System.arraycopy(account, 0, newaccount, 0, account.length);
thats gives an error
: <identifier> expected
and when if i put it after the i++ in the create listner it says variable account not found

The whole function should look like:
