In Java, I have to modify the code

For the loan payments, the user is to choose whether the loan is for a mortgage, a student loan, an auto loan, or a personal loan. For Mortgage: assume $350,000 balance and payment of $3500 per month; For Student Loan: assume $75,000 balance and payment of $250 per month; For Auto Loan, assume $35,000 balance and payment of $500 per month; For Personal Loan, assume $5,000 and payment of $1000 per month.

Test data: for savings account in order: deposit $2000, deposit $1500, withdraw $2500, final balance

Test data for checking account in order: checks (in order) made in the amount of $120, $40, $700, $50, $1000, final balance.

Test data for loan payment(s): see above and provide for at least two payments.

This is the code I have to modify:
