Constructor Detail

Cylinder

public Cylinder()

Construct a Cylinder object using the default value for radius and depth.

Cylinder

public Cylinder(double theRadius,
                double theDepth)

Construct a Cylinder object using the arguments. If an argument is <= 0.0, the default value (Shape.DEFAULT_SIZE is used instead.

Parameters:

theRadius - the radius for this Cylinder

theDepth - the depth for this Cylinder

Cylinder

public Cylinder(Cylinder x)

This is the copy constructor.

Parameters:

x - is the Cylinder to be duplicated.

Method Detail

getSurfaceArea

public double getSurfaceArea()

Get the surface area of this Cylinder. Overridden from Circle.

Overrides:

getSurfaceArea in class Circle

Returns:

the surface area of this Cylinder

getPerimeter

public double getPerimeter()

Get the perimeter of this Cylinder. (2*2*radius*pi) Overridden from Circle.

Overrides:

getPerimeter in class Circle

Returns:

the perimeter of this Cylinder

getVolume

public double getVolume()

Get the volume of this Cylinder. (radius*radius*pi*depth)

Specified by:

getVolume in interface ThreeD

Returns:

the volume of this Cylinder

getDepth

public double getDepth()

Get the depth of this Cylinder.

Specified by:

getDepth in interface ThreeD

Returns:

the depth of this Cylinder

setDepth

public void setDepth(double theDepth)

Reset the depth of this Cylinder. If d is <= 0, the dimension is unchanged.

Specified by:

setDepth in interface ThreeD

Parameters:

theDepth - the new depth of this Cylinder; must be > 0

toString

public java.lang.String toString()

Returns a String object representing this Cylinder's value. Overridden from Object.

Overrides:

toString in class Circle

Returns:

a string representation of this object

equals

public boolean equals(java.lang.Object o)

Returns true if and only if the argument is not null and is a Cylinder object that has the same radius and depth as this Cylinder.

Overrides:

equals in class Circle

Parameters:

o - is the object to be compared with.

Returns:

true if the Cylinder object argument has the same radius and depth, false otherwise.

compareTo

public int compareTo(ThreeD a)

Using getVolume to determine the comparison result as follows:
-1 if (this.getVolume() < a.getVolume());
0 if (this.getVolume() = a.getVolume());
1 if (this.getVolume() > a.getVolume());

Specified by:

compareTo in interface java.lang.Comparable<ThreeD>

Parameters:

a - is a ThreeD object

Returns:

-1, 0, 1, standard meaning of compareTo.
