Constructor Detail

RectanglePrism

public RectanglePrism()

Construct a Cube object using the default size for its length, height and depth.

RectanglePrism

public RectanglePrism(double theLength,
                      double theHeight,
                      double theDepth)

Construct a Cube object using the arguments. If an argument is <= 0, the default size specified in Shape is used instead.

Parameters:

theLength - the length of this Cube; must be > 0

theHeight - the height of this Cube; must be > 0

theDepth - the depth of this Cube; must be > 0

RectanglePrism

public RectanglePrism(RectanglePrism x)

This is the copy constructor.

Parameters:

x - is the RectanglePrism to be duplicated.

Method Detail

getSurfaceArea

public double getSurfaceArea()

Get the surface area of this Cube.

Overrides:

getSurfaceArea in class Rectangle

Returns:

the surface area of this Cube

getPerimeter

public double getPerimeter()

Get the perimeter of this Cube.

Overrides:

getPerimeter in class Rectangle

Returns:

the perimeter of this Cube

getVolume

public double getVolume()

Get the volume of this RectanglePrism.

Specified by:

getVolume in interface ThreeD

Returns:

the volume of this RectanglePrism

getDepth

public double getDepth()

Get the depth of this Cube.

Specified by:

getDepth in interface ThreeD

Returns:

the depth of this Cube

setDepth

public void setDepth(double theDepth)

Set the depth of this Cube.

Specified by:

setDepth in interface ThreeD

Parameters:

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

toString

public java.lang.String toString()

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

Overrides:

toString in class Rectangle

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 RectanglePrism object that has the same length, height and depth as this RectanglePrism.

Overrides:

equals in class Rectangle

Parameters:

o - is the object to be compared with.

Returns:

true if the RectanglePrism object has the same length, height 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.
