Struggling with Loan problem

Hi there. I´m struggling with coding the Loan Problem at the end of Module 2 Java. The problem: ----------------------- Loan Calculator You take a loan from a friend and need to calculate how much you will owe him after 6 months. You are going to pay him back 10% of the remaining loan amount each month. Create a program that takes the loan amount as input, calculates and outputs the remaining amount after 6 months. Sample Input: 20000 Sample Output: 10628 -------------------------------------- My code: https://code.sololearn.com/cA172a19a181/# However, I get a 'No output' . The question is why I´m not getting any output. Is there anything wrong in the FOR loop? Thanks in advance

There are some illegal character errors ,I removed the spaces from for loop and it outputs 10629 for 20000

Thanks so much for the answer Abhay. I removed the spaces from the FOR loop and I´m do getting outpout 53145 for 100000, when the expected is 53144. I will have to figurate out how to do the exact math operation. Regards

Enrique Guia In case you haven't figured out a solution, making use of float variables outputs 10628.82 in my case and 53144.1 in your case .

Use 90% for 6 months to find the balance. 4 lines of code added. https://code.sololearn.com/cp6GXE4Rc84v/?ref=app If you are paying 10% every month, one way is to find the 10% and then use your total minus the 10% paid to get the balance. The other way, is to find the 90% so you don't have to minus. If you have 100 and you paid 10%, Method 1: 100 - (100 * 10%) = 90 Method 2: 100 * 90% = 90 The "i=0" is used for looping. It will loop from 0 until 5 (< 6), which is 6 times. Finally prints out amount.

Enrique Guia https://code.sololearn.com/cp6GXE4Rc84v/?ref=app The reason why you get 54145 is because of Integer division. It ignores decimals (rounding down). Ultimately when you do a minus, you get an extra 1. 1: 100000 - 100000/10 = 90000 2: 90000 - 90000/10 = 81000 3: 81000 - 81000/10 = 72900 4: 72900 - 72900/10 = 65610 5: 65610 - 65610/10 = 59049 6: 59049 - 59049/10 = 59049 - 5904 (missing precision) = 54145 (extra 1, expected 54144) To bypass, you can do "amount = amount * 90 / 100". Do not hard-code -1 or +1. One good example will be 0. After 6 months, it will still be 0. By hard-coding -1, it results in -1 which is wrong.

Thanks for your advice, but at the end of the problem there is the following requirement: -- Use a loop to calculate the payment and remaining amounts for each month. Also, use integers for amounts. --
