Create a GasStation class that represents the gas station. This class should have fields to store the gas prices, stock levels, and account balance.
public class GasStation {
private double regularGasPrice;
private double premiumGasPrice;
private double dieselGasPrice;
private int regularGasStock;
private int premiumGasStock;
private int dieselGasStock;
private double accountBalance;
// Getters and setters for the fields
...
}
Create a Sale class that represents a single sale of gas. This class should have fields to store the type of gas, the number of gallons sold, and the price per gallon.
public class Sale {
private GasType gasType;
private double gallonsSold;
private double pricePerGallon;
// Getters and setters for the fields
...
}
Create an enumeration GasType that represents the different types of gas sold at the gas station.
public enum GasType {
REGULAR,
PREMIUM,
DIESEL
}
Implement methods in the GasStation class to handle the sale of gas and update the stock levels and account balance accordingly.
public class GasStation {
...
public void sellGas(Sale sale) {
GasType gasType = sale.getGasType();
double gallonsSold = sale.getGallonsSold();
double pricePerGallon = sale.getPricePerGallon();
switch (gasType) {
case REGULAR:
regularGasStock -= gallonsSold;
accountBalance += gallonsSold * pricePerGallon;
break;
case PREMIUM:
premiumGasStock -= gallonsSold;
accountBalance += gallonsSold * pricePerGallon;
break;
case DIESEL:
dieselGasStock -= gallonsSold;
accountBalance += gallonsSold * pricePerGallon;
break;
}
}
}
Implement methods to retrieve the stock levels and account balance for each type of gas and for the gas station as a whole.
public class GasStation {
...
public int getRegularGasStock() {
return regularGasStock;
}
public int getPremiumGasStock() {
return premiumGasStock;
}
public int getDieselGasStock() {
return dieselGasStock;
}
public double getAccountBalance() {
return accountBalance;
}
}
This is just a basic outline of a Java project for the operations of a gas station. You can add additional functionality as needed, such as methods to update the gas prices or to print reports of the sales and stock levels.
