Answer:

See explaination

Explanation:

//Cylinder.java

public class Cylinder extends Circle {

private double height;

public Cylinder(double h, double r) {

super(r);

setHeight(h);

}

public double getHeight() {

return height;

}

public void setHeight(double height) {

this.height = height;

}

public boolean equals(Object o) {

if (this == o) return true;

if (!(o instanceof Cylinder)) return false;

Cylinder cylinder = (Cylinder) o;

return Double.compare(cylinder.height, height) == 0 && Double.compare(cylinder.radius, radius) == 0;

}
