Thread: paying off dept ( can't make it stop at 0 )

Heey,

I'm having a problem with this code. It doesn't want to stop at 0.

public class Main {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        double schuld = 100000;
        double rp = 9.0;
        double rente;
        double af = 15000;
        double sum;
        int jaar = 1;
 
        sum = 0;
        rente = (schuld/100) * rp;
 
        System.out.println("Jaar   Schuld   Rp   Rente  Aflossing");
        System.out.println(jaar + "    " + schuld + "    " + rp + "   " + rente + "   " + af);
 
 
        while (schuld >= 0){
 
            rente = (schuld/100) * rp;
            schuld = (schuld + rente) - af;
            jaar++;
            System.out.println(jaar + "    " + schuld + "    " + rp + "   " + rente + "   " + af);
       if(schuld == 0)
           schuld = sum;
        }
     }
}

Can anyone please help me?

Next time please surround your code in [highlight=java][/highlight] tags.

Well... Your while loop says >= 0. Either change your loop to

while (schuld > 0){

or change this line

sum = -1;

paying off dept ( can't make it stop at 0 )

Isn't that more like real life though?

Seriously though, Brty93yoda is correct. The case you specify in the while loop is the case in which it will leave. This is important because the case is evaluated BEFORE it runs the loop (unlike a Do-While). So when schuld is equal to 0 and you are expecting it to do the loop 1 more time, it actually meets the condition of schuld>=0 and it leaves the loop right then.
