Loan Calculator (JAVA) How is this possible?

Question

In the Java course they asked me to make a Loan calculator. I used the code below to solve this. My question is, how does the line of code below work? Shouldn’t the ouput be zero because 9/10 equals zero?

amount = amount * 9/10

CODE I USED IS BELOW:

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 x = 1; x <= 6; x++){
amount = amount * 9/10;
}
System.out.println(amount);
}
}

Answer 1

Sol , if you place it this way (9/10) in brackets in the equation - yes the output is 0, in the other case it depends - first you multiply amount with 9 then you divide it by 10. As a hint for payment for each month you can use Math.ceil method.

Answer 2

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.

TheWh¡teCat 🇧🇬 That makes more sense, thank you! Considering the order of operations rule (PEMDAS), the code is executed from left to right.

Sol , you are welcome 🐱

Answer 6

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
int rem_amt = amount;
for (int i = 1 ; i <= 6 ; i++) {
int paid = (int)Math.ceil(10/100.0*rem_amt);
rem_amt -= paid ;
}
System.out.println(rem_amt);
}
}

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
int rem_amt = amount;
for (int i = 1 ; i <= 6 ; i++) {
int paid = (int)Math.ceil(10/100.0*rem_amt);
rem_amt -= paid ;
}
System.out.println(rem_amt);

}
}

Answer 8

Scanner sc = new Scanner (System.in);
int amount = sc.nextInt();
int payment;
int rem_Amt;

for(int i = 0; i<=3; i++){

payment = amount * 10/100;
amount = amount - payment;

System.out.println(amount);
}

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
int rem_amt = amount;
for (int i = 1 ; i <= 6 ; i++) {
int paid = (int)Math.ceil(10/100.0*rem_amt);
rem_amt -= paid ;
}
System.out.println(rem_amt);

}
