Loan calculator challenge

Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

for (int month = 1; month <=6; month = month + 1){
int tax= amount /10;
int newAmount= amount - tax;

System.out.println(newAmount);

}

}
}
I got the code to print out the first month amount but i do not know how to get the equation to repeat

Answer 1

So Sovanrotha i did figure it out
import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

for (int month = 1; month <=6; month = month + 1){

amount= (int)amount - (int)Math.ceil(0.1 * amount);
}

System.out.println(amount);

}
}

Answer 2

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amt = scanner.nextInt();
//your code goes here
for(int i=0;i<6;i++)
{
amt=(int)amt-(int)Math.ceil(0.1*amt);
}
System.out.print(amt);
}
}

Look at the problem then look at this you will understand what i did

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.

Answer 4

《 Nicko12 》 thank you i removed the extra variable and got it to repeat the equation but the answer is off by 1 for some reason

Answer 5

And if i use int like the questiom says to all of the answers are 1 off

Answer 6

《 Nicko12 》 this is where i am at and the answers are off by 1

Answer 7

《 Nicko12 》 you did thank you!

Answer 8

Coder YES! That worked thank you so much!

Answer 9

Use 90% for 6 months to find the balance.
4 lines of code added.

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.

Answer 10

Dennoun Jawad It's purposely hidden so no hard-coding can be done to cheat the system. At the same time, to strengthen problem-solving.

Answer 11

Ben Szydlowski that is exactly my problem, I don't get why it's off by 1

Answer 12

if you cast the system.out.println you dont need to subtract.
println((int)amount) will convert it back to an int

Answer 13

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

for (int month = 1; month <=3; month = month + 1){
int tax= amount /10;
amount= amount - tax;
}
System.out.println(amount);

}
}

This is the right a answer for loan calculator

Answer 14

I used the double and found that the answer needs to round down and become an int

Answer 15

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
double amount = scanner.nextInt();
//your code goes here

for (int month = 1; month <=6; month = month + 1){
double tax= amount /10;
amount= amount - tax;
}
System.out.println(amount);

}
}

This is where im at

Answer 16

《 Nicko12 》 i do not know why but i got the first test correct but the 2nd is off by 1 still

Answer 17

《 Nicko12 》 That code doesn't come out with the correct number

Answer 18

Yeah, the number is so slightly off so it must be the math somewhere is wrong but i dont know where

Answer 19

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

for (int month = 1; month <=6; month = month + 1){
int tax= amount / 10;
amount= amount - tax;
}

System.out.println(amount);

}
}

Answer 20

The problem i had was i over complicated it and put too many variables and had to just condense it into one variable and equation
