Crisis with co2 footprint program

[gibson.nathan]

what i am trying to do is take alot of information and use it to calculate a persons carbon footprint based on a list of things that are in the second class of my program. im trying to make everything very easy to read program wise. im doing this assignment and i got in over my head trying to get it done. im trying to work down from bigger problems to specific questions, but at this point i would greatly appreciate it if you guys could point out some of my errors that i am not catching. if anyone can help it is most def appreciated. im super lost and i have to get this done.

also i forgot to include that these are some of the requirements that i have to complete.

7. Create a minimum of five different objects.
8. Your CO2 footprint should account for the
following:
• annual estimate of gasoline used
• annual estimate of electricity used
• annual household waste produced
• annual household waste recycled
• replacement of incandescent bulbs
9. The constructor should include the following parameters:
• annual gasoline used
• average electricity bill and average electricity price
• number of people in home
• recycle paper, plastic, glass, or cans (Booleans)
• number of light bulbs replaced

i have been working for a while and still havent quite gotten far. i have a specific place where im stuck though.

gasFootprint = CO2Footprint.calculateGasEmissions(gas);

it says no static method can not be referenced as a static context

[Ezzaral]

Because you are calling that method statically but it is not declared as a static method. To call it as you have defined it, you would need to create an object of that type and call the method on it.

That method doesn't return anything though, so trying to capture a return value from it won't get you anywhere.

i have read your response and been working on trying to fix it for tha last hour. can you please help me out? so far i have got this for the first class.

So now you can create a CO2Footprint object and call methods on it

CO2Footprint footprint = new CO2Footprint();
double[] glassReduct = footprint.calcGlassReductions();

CO2Footprint footprint = new CO2Footprint();
