Because of energy conservation, ecology and the high price of gasoline, drivers are concerned with the mileage obtained by their auotomobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a Java applet that will input the miles driven and gallons used (both as integers) for each tankful. The program should calculate and display the miles per gallon obtained for each tankful and print the combined miles per gallon obtained for all tankfuls up to this point. All averages calculations should produce floating-point results. Use two TextField to input the data..
