Question

The solution works, but the iteration keeps looping to month 1 within the for loop. I need to find out how to get the following Output: Enter the savings account's balance: 10000 Enter the savings account's annual interest rate: .02 How many months have passed since the account was opened? 3 Enter the amount deposited during month 1: 1200 Enter the amount withdrawn during month 1: 900 Enter the amount deposited during month 2: 1500 Enter the amount withdrawn during month 2: 1100 Enter the amount deposited during month 3: 2000 Enter the amount withdrawn during month 3: 1800 Total Deposited: $4,700.00 Total withdrawn: $3,800.00 Interest Earned: $53.25 Ending Balance: $10,953.25 What I need help with is having the program iterate 3 times because the user entered 3 for how many months the account has been opened. And the set precision for dollar amounts. This is an intro to Java class so simple code is needed here, I wouldn't understand any advanced code. Thank You!
