Constructor Detail

IPoint3D

public IPoint3D()

Constructs a point with coordinates (0.0, 0.0).

IPoint3D

public IPoint3D(double x,
        double y)

Constructs a point with coordinates (x, y).

Parameters:

x - the x coordinate

y - the y coordinate

Method Detail

getX

public double getX()

Returns the x coordinate of this point.

Returns:

the x coordinate of this point

getY

public double getY()

Returns the y coordinate of this point.

Returns:

the y coordinate of this point

getZ

public double getZ()

Returns the z coordinate of this point.

Returns:

the z coordinate of this point

distanceTo

public double distanceTo(IPoint3D other)

Returns the distance between this point and another point.

Parameters:

other - the point to compute the distance to

Returns:

the distance between this point and other

equals

public boolean equals(Object obj)

Compares this point to another object. The result is true if and only if the argument is not null and is an IPoint3D object that has the same coordinates of this object.

Overrides:

equals in class Object

See Also:

Object.equals(java.lang.Object)

Parameters:

obj - the other object to compare

Returns:

true if obj is an IPoint3D object with the same coordinates as this object

toString

public String toString()

Returns a string containing the coordinates of the point separated by a space and a comma and inside square brackets. No special formatting is applied to the coordinates. For example: (new IPoint3D(-1.5, 3.1415)).toString() returns the string "(-1.5, 3.1415)".

Overrides:

toString in class Object

See Also:

Object.toString()

Returns:

a string representation of the point
