Answer:
Explanation:
The following code is written in Java. I recreated the entire Child class as described with the instance variables and the doubleWeight method. Then created the getter and setter methods for both the weight and height variables.
class Child {
double weight, height;
public double doubleWeight() {
double superWeight = weight * height;
return superWeight;
}
public double getWeight() {
return weight;
}
public void setWeight(double weight) {
this.weight = weight;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
}
