double energyReserves;

boolean isHungry() {
return energyReserves < 2.5;
}
void eat(Food f) {
energyReserves += f.getCalories();
}
public static void main(String[] args)
{
thePig = new Animal();
theCow = new Animal();
if (thePig.isHungry()) {
thePig.eat(tableScraps);
}
if (theCow.isHungry()) {
theCow.eat(grass);
}
}
}
/*In the above example, the class Animal is an abstraction used in place of an actual animal.*/
