I'm trying to figure out how to transfer several methods in a cash register into one void method. Here is my code.
/**
* A cash register totals up sales and computes change due.
*/
public class CashRegister
{
private double purchase;
private double payment;
/**
* Constructs a cash register with no money in it.
*/
public CashRegister()
{
purchase = 0;
payment = 0;
}
/**
* Records the sale of an item.
* @param amount the price of the item
*/
public void recordPurchase(double amount)
{
double total = purchase + amount;
purchase = total;
}
/**
* Enters the payment received from the customer.
* @param amount the amount of the payment
*/
public void enterPayment(double amount)
{
payment = amount;
}
/**
* Computes the change due and resets the machine for the next customer, and
* Print a receipt.
*/
public void printReceipt()
{
double change = payment - purchase;
System.out.printf(" Total Sales: $ %.2f\n", purchase);
System.out.printf(" Payment: $ %.2f\n", payment);
System.out.printf("==========================\n");
if (payment < purchase) {
System.out.printf("Not Enough Payment: $ %.2f\n\n", change);
}
else {
purchase = 0;
payment = 0;
System.out.printf(" Change Due: $ %.2f\n\n", change);
}
}
}
This is the class with the separate method. I want the methods in that to run in the code below.
public class RunCashRegister
{
public void run()
{
}
}
Help would be most appreciated as I am very new to java. Thank you.
