i upload the code also for the checkingaccount.java and goldaccount.java and regularaccount.java and account.java in case if you need to fix them in order to fix the problem that facing me.

Please Do not answer if your not fixing the problem first you need to understand what is my problem and then take a look to the code and then fix it please and upload the code for me to test it please.

Thank you in advance
