Thread: Boolean method help!

Hello all!

So, I'm creating a program that deals with a discount loyalty system. When the customer buys $100.00 worth of items, they get a $10.00 discount. This discount needs to be a boolean method (discountReached()). Thus far, I have:

class Customer {
 
//Declare variables
double totalCost;
double discount = 10;
 
 
public Customer() {
totalCost = 0;
}
 
public void makePurchase(double amount) {
totalCost = totalCost + amount;
}
 
public double getTotal() {
return totalCost;
}
 
 
 
}

So, I have the total amount all worked out. Now I don't know how to go about having the boolean method ONLY run once when the total reaches over $100.00.

Any help is appreciated!

Thanks,

Okay, but I'm not sure how to make the boolean method work, either. I guess I would start like:
public boolean discountReached() {
totalCost - 10;
return totalCost;
}
