Why is this giving me an infinite loop?
- by Chase Yuan
I was going through a code used to calculate investments until it has doubled and I received an infinite loop that I can't seem to solve. Can anyone figure out why this is giving me an infinite loop? I've gone through myself but I can't seem to find the problem. The "period" referred is how many times per year the interest is compounded.
double account = 0; //declares the variables to be used
double base = 0;
double interest = 0;
double rate = 0;
double result = 0;
double times = 0;
int years = 0;
int j;
System.out.println("This is a program that calculates interest.");
Scanner kbReader = new Scanner(System.in); //enters in all data
System.out.print("Enter account balance: ");
account = kbReader.nextDouble();
System.out.print("Enter interest rate (as decimal): ");
rate = kbReader.nextDouble();
System.out.println(" " + "Years to double" + " " + "Ending balance");
base = account;
result = account;
for (j=0; j<3; j++){
System.out.print("Enter period: ");
times = kbReader.nextDouble();
while (account < base*2){
interest = account * rate / times;
account = interest + base;
years++;
}
account = (((int)(account * 100))/100.0);
//results
System.out.print(" " + i + " " + account + "\n");
account = result;
}
The code should ask for three "periods", or three different times the entered data is compounded per year (ex annually, monthly, daily etc.)
Thanks a lot!
