Write a new class called DistanceFitnessTracker that extends FitnessTracker . DistanceFitnessTracker will represent a fitness tracker able to
record only distance. In this Problem Sheet, you will not be asked to convert between distance units
(i.e. the default behaviour of the Distance class will be used, namely, kilometres)
In simple words distancefitnesstracker I provided is incomplete it needs to pass the test I provided
I need my distancefitnesstracker:
public class DistanceFitnessTracker extends FitnessTracker{
private Distance distance;
public DistanceFitnessTracker(String modelName, Distance distance) {
super(modelName);
this.distance = distance ;
}
public Distance getDistance() {
return distance;
}
}
To pass this Junit test code:
public class TestDistanceFitnessTracker {
@Test
public void testTrackersDifferentSumNotEqual() {
DistanceFitnessTracker a = new DistanceFitnessTracker("hr", new Distance(20));
DistanceFitnessTracker b = new DistanceFitnessTracker("hr", new Distance(20));
b.addDistance(new Distance(10));
assertNotEquals(a, b);
assertNotEquals(b, a);
}
}
To make it simple the I need to implement distancefitnesstracker to store a distance and to pass the JUNit test I provided
