String miles;
String gallons;
double MPG;
double miles1, gallons1;

miles=JOptionPa ne.showInputDia log("Enter the number of miles driven : ");

miles1=Double.p arseDouble(mile s);
gallons1=Double .parseDouble(ga llons);

MPG = miles1 / gallons1;

JOptionPane.sho wMessageDialog( null,"Your Car's Mileage is : " + MPG + "\n");
System.exit(0);
