Java : Code Project (Loan Calculator)

Question

You take a loan from a friend and need to calculate how much you will owe him after 3 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 3 months.

I want to know if I did this the right way because it felt like I was doing it wrong in a way.
Can someone please assist me.

Here is my code :

edited: int amount = scanner.nextInt();

for (int month = 1; month <= 3; month++){
//month 1
int remainderMonth1 = (int) (amount * 0.1);//2000
int remainder1 = (int) (amount - remainderMonth1); //18 000

//month 2
int remainderMonth2 = (int) (remainder1 * 0.1); //1800
int remainder2 = (int) (remainder1 - remainderMonth2); //16200
//month 3
int remainderMonth3 = (int) (remainder2 * 0.1);
int remainder3 = (int) (remainder2 - remainderMonth3);
System.out.println(remainder3);
break;
}

I didnt add the input here but ( Amount is the input )

Answer 1

You have coded that what the loop should do. In the example I present another way, you can follow for the variable „amount2“:
