The method drive() generates a random number of miles for one segment of a trip. Then I needed to cannot be write code to check to see if the gas tank is empty. If it is, do not allow movement of the car. If it isn't, call the burnGas() method of in the GasTank class. Then the printTripDetails() method is called to show the current status of the trip. Well, when I set up the If statement to check if the cannot be applied gas tank was empty, I get the following error message, which is Greek to me and I'm so confused. I have tried so many different things and nothing is working!! I'm really concerned that this is super simple stuff that I can't figure out and if I'm not understanding this then maybe I'm in the wrong field?? method burnGas in class GasTank cannot be applied to given types; required: double, double found: no arguments reason: actual and formal argument lists differ in length The operator that you use here cannot be used for the type of value that you are using it for. You are either using the wrong type here, or the wrong operator. Here is the code for Car, which probably has more errors than just what I've mentioned here: import java.util.Random; public class Car{ //the manufacturer of the car String make; //the model of the car String model; //the miles per gallon double mpg; double totalMilesDriven; //the GasTank GasTank tank; double tripDistance; /* * constructor for a default Car object */ public Car(){
