Thread: Help me with this code.

I am a beginner. This is an assignment given my class teacher. I have designed a class named Bank. Here I want to OPEN ACCOUNT, DEPOSIT MONEY, WITHDRAW MONEY and PRINT STATEMENT. My problem is in the PRINT STATEMENT method. I want to show, TIME, DATE, and last OPERATION(withdraw or deposit) and OPERATION AMOUNT. Now, I don't understand how I can get the last operation (whether it is withdraw or deposit?) and amount. Please see my code and do please help me. I have to submit it anyway, it will give me 10 marks. Do please help me.

Thanks in advance.

Why not add another instance variable to track the previous operation, you could use booleans or strings to accomplish it
