Constructor Detail

Rectangle

public Rectangle()

Construct a Rectangle object using the default size for its dimensions.

Rectangle

public Rectangle(double theLength,
                 double theHeight)

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

Parameters:

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

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

Rectangle

public Rectangle(Rectangle x)

This is the copy constructor.

Parameters:

x - is the Rectangle to be duplicated.

Method Detail

getSurfaceArea

public double getSurfaceArea()

Get the surface area of this Rectangle. (length*height;)

Specified by:

getSurfaceArea in class Shape

Returns:

the surface area of this Rectangle

getPerimeter

public double getPerimeter()

Get the perimeter of this Rectangle.

Specified by:

getPerimeter in class Shape

Returns:

the perimeter of this Rectangle

getLength

public double getLength()

Get the length dimension of this Rectangle.

Returns:

the length of this Rectangle

getHeight

public double getHeight()

Get the height dimension of this Rectangle.

Returns:

the height of this Rectangle

setLength

public void setLength(double theLength)

Set the length dimension of this Rectangle. If theLength is <= 0, the dimension is unchanged.

Parameters:

theLength - new length of this Rectangle; must be > 0

setHeight

public void setHeight(double theHeight)

Set the height dimension of this Rectangle. If theHeight is <= 0, the dimension is unchanged.

Parameters:

theHeight - the new height of this Rectangle; must be > 0

toString

public java.lang.String toString()

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

Overrides:

toString in class java.lang.Object

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 Rectangle object that has the same length and height as this Rectangle.

Overrides:

equals in class java.lang.Object

Parameters:

o - is the object to be compared with.

Returns:

true if the Rectangle object has the same length and height, false otherwise.
