Loan calculator

Question

Result of my code matched with needed answer but still it doesn’t accept my code:

int months = 6;
while(months > 0){
amount = (int)Math.floor(amount * 0.9);
System.out.println(amount);
months--;
}
Why so? Can someone tell me please?:)

Answer 1

oh, i see.. tnx

Answer 2

You should check the test results in more detail. Compare your output with the expected output. You are printing several amount (in each loop cycle) but you should only print the final result.

Answer 3

Use 90% for 6 months to find the balance.

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.
