Question

In JAVA

We used two types of lights: incandescent and flourescent. All lights output an amount of light measured in lumens. Incandescent lights also output a significant amount of heat, while flourescent lights output almost no heat (none for the purposes of this labtask). The amount of heat output by an incandescent light is 87.4 times the lumens of the light. While flourescent lights are cool, they are also harder to control - they are always either "on" or "off", so are therefore less useful in the theatre where effect is required. Thus, in any theatre light strip, it is important to monitor the total light output, the total heat output, and the number of flourescent lights.

In some initial analysis, design, and implementation, I produced an abstract superclass Light.java, and also a control program RunLights.java. You must implement the classes that represent incandescent lights, flourescent lights, and light strips. (The class for light strips must use a Vector to hold the lights in the strip.) With those completed, here's what a sample run should look like (with the keyboard input shown in italics) ...

Flourescent.java
----------------

public class Flourescent extends Light {

public Flourescent(int lumens) {
super(lumens);
}

@Override
public double heatOutput() {
return 0;
}

@Override
public boolean isFlourescent() {
return true;
}

public String toString()
{
return "Flourescent light of " + getLumens() + " lumens";
}

}

Incandescent.java
---------------
public class Incandescent extends Light{

public Incandescent(int lumens) {
super(lumens);
}

@Override
public double heatOutput() {
return 87.4 * getLumens();
}

@Override
public boolean isFlourescent() {
return false;
}

public String toString()
{
return "Incandescent light of " + getLumens() + " lumens";

}

}

LightStrip.java
----------
import java.util.Vector;

public class LightStrip {
Vector<Light> lights;

public LightStrip()
{
lights = new Vector<Light>();
}

public void display() {
double totalLumens = 0;
double heat = 0;
int fCount = 0;

for(int i = 0; i < lights.size(); i++)
{
System.out.println(i + ": " + lights.get(i));
totalLumens += lights.get(i).getLumens();
heat += lights.get(i).heatOutput();
if(lights.get(i).isFlourescent())
fCount++;
}

System.out.printf("Total lumens = %.1f ", totalLumens);
System.out.printf("Flourescent = %d ", fCount);
System.out.printf("Heat output = %.1f ", heat);

}

public void addLight(Light light) {
lights.add(light);
}

public void removeLight(int index)
{
if(index >= 0 && index < lights.size())
lights.remove(index);
else
System.out.println("ERROR: No light at that index");
}
}
