im relatively new to trying to program in oop. i have been slowly working through this entire program learning as i go. i have gotten this class to compile.

im working on this trying to get it to work but i am getting a .class expected on my constructor thing. if anyone can help it is appreciated.

Hi gibson.nathan,

In your CO2FootPrintTester

public class CO2FootPrintTester
{
        public static void main(String[] args){
// remove this, it shouldn't be here
CO2Footprint( int numberOfPeople, double gasFootPrint, double averageElectricBill, 
        double averageElectricPrice, boolean paperRecyled, boolean plasticRecyled, boolean glassRecyled,
        boolean cansRecyled, int numLightsRecyled, double totalReductionsPaper, double totalReductionsPlastic,
        double totalReductionsGlass, double totalReductionsCans, double electricityEmissions)

and then

// you don't have a constructor without parameters for the CO2Footprint class
CO2Footprint fp0 = new CO2Footprint(); 
         fp0.numPeople = 3;
         fp0.gas = 2604;
         fp0.aveElecBill = 227.29;
         fp0.aveElecPrice = 0.084;
         fp0.paper = true;
         fp0.plastic = true;
         fp0.glass = true;
         fp0.cans =  true;
         fp0.numLights = 9;
// replace the above with 
         CO2Footprint fp0 = new CO2Footprint(3, 2604, 227.29, 0.084,  true, true, true, true, 9);
// this is how you call the constructor defined for your CO2Footprint class
