OOPAnnualFuelUse All I need to know is if I am on the right track in terms of min and max, not neccessarily how to finish the program.
Please, reply yes or no, and if no, why.
And for the tester// here is what I have class AnnualFuelUse { // instance variables - replace the example below with your own private int day, sMiles, eMiles, dist; private double gUsed, mpg, ppg, cost; public AnnualFuelUse(int dy,int sM,int eM,double gU, double pPg) { // initialise instance variables day = dy; sMiles = sM; eMiles = eM; gUsed = gU; dist = 0; ppg = pPg ; mpg = 0.0; cost = 0.0; } public void calcDistance() { dist = eMiles - sMiles; } public int getDistance() { // put your code here return dist; } public void calcMPG() { // put your code here mpg = ((dist)/(gUsed)); } public double getMPG() { // put your code here return mpg; } public void calcCosts() { cost = (mpg * ppg); } public double getCost() { return cost; } }
I made some changes to tester again please review!?public class AnnualFuelUseTester { public static void main (String[] Args) { AnnualFuelUse[] aFUT = { new AnnualFuelUse(1, 45023, 45231, 10.00, 2.95), new AnnualFuelUse(4, 45231, 45480, 11.70, 2.99), new AnnualFuelUse(8, 45480, 45659, 9.30, 2.99) }; double [] mpg = new double[3]; double [] cost = new double[3]; double [] distance = new double[3]; for(int i = 0; i < distance.length; i++) { aFUT[i].calcDistance(); distance[i] = aFUT[i].getDistance(); } for(int i = 0; i < mpg.length; i++) { aFUT[i].calcMPG(); mpg[i] = aFUT[i].getMPG(); } for( int i = 0; i < cost.length; i++) { aFUT[i].calcCosts(); cost[i] = aFUT[i].getCost(); } double max = Double.MIN_VALUE; double min = Double.MAX_VALUE; for(int i = 0; i < 3; i++) { if( distance[i]> max) max = distance[i]; } for(int i = 0; i < 3; i++) { if( distance[i]< min) min = distance[i]; } double max1 = Double.MIN_VALUE; double min1 = Double.MAX_VALUE; for(int i = 0; i < 3; i++) { if( mpg[i]> max1) max1 = mpg[i]; } for(int i = 0; i < 3; i++) { if( mpg[i] < min1) min1 = mpg[i] ; } double max2 = Double.MIN_VALUE; double min2 = Double.MAX_VALUE; for(int i = 0; i < 3; i++) { if( cost[i]> max2) max2 = cost[i]; } for(int i = 0; i < 3; i++) { if( cost[i] < min2) min2 = cost[i] ; } } }
