question about arrays

I am doing a bank project where we record deposits and withdrawals using positive and negative numbers. Using arrays we store the numbers, positive numbers being deposits and negative numbers being withdrawals. I have a method where all deposits and withdrawals are printed:

public void showAll() {
int index=0;
while (index < auditTrail.size())
{
System.out.println(auditTrail.get(index));
index++;
}
}



However I need a method where only deposits are printed and one where only withdrawals are printed. any advice would be much appreciated.

As you title says, use two separate arrays for withdraws and deposits. You have to decide the array size, depend on your requirements.

ok, then how do i fix showAll()

Just declare an appropriate array (size and data type) inside the showAll(). You can pass all required data from outside.
