2. This part asks you to modify the Java program you just created. The gas station only has a finite amount of each type of gas. Add instance variables that track how many gallons of each type of gas the station has to sell. You can fix the initial value to be 1000 gallons each. Add a method to print current supply Modify the sellregular/super methods to subtract from supply after each sale. 2b. Further modify the sellregular/super methods to call the internal gouge() function when the total supply of gass drops below 200 gallons. Now you have to becareful that this should only be called once: For example: A->currentSupply(); // say current supply is 210 gallons (regular+super) A->sellregular(20); // supply now 190 gallons, CALL GOUGE to double prices A->sellregular(10); // supply now 180 gallons, but DON'T call gouge again! You may need to declare additional variables, maybe even functions, to implement this algorithm correctly.

public class lab1 { public static void main(String[] argc) { gasStation A = new gasStation(2.69, 3.09); gasStation B = new gasStation(2.49, 2.99); A.sellregular(10); A.sellsuper(8); B.sellsuper(11); B.sellregular(12); if(A.moreprofits(B)) System.out.println("Station A is more prifotable. "); else System.out.println("Station B is more profitable. "); gasStation[] G = new gasStation[10]; for(int i=0;i<10;i++) G[i]=new gasStation(2.59,3.19); for(int i=0;i<10;i++) { G[i].sellregular((int)(Math.random()*26+77)); G[i].sellsuper((int)(Math.random()*26+77)); } gasStation highest = G[0]; for(int i=1;i<10;i++) { System.out.println(G[i].getsales()); if(G[i].moreprofits(highest)) highest = G[i]; } System.out.println("highest total sales is: "+highest.getsales()); } }
