Can a programmer write a definition for the class Car
?
Of course!
Here is the miles per gallon program. To keep the program short, user interaction has been left out.
class Car { // instance variables // constructor // methods } class MilesPerGallon { public static void main( String[] args ) { Car car = new Car( 32456, 32810, 10.6 ); System.out.println( "Miles per gallon is " + car.calculateMPG() ); } }
The source file must be named
MilesPerGallon.java
after the name of
the class that contains main()
.
Decide what variables should go in the data section. Look back to the Car class for the class to see what you need.
