The Point object represents a location in a two-dimensional coordinate system, where x represents the horizontal axis and y represents the vertical axis.
The following code creates a point at(0,0):
Methods and properties of the following classes use Point objects:
You can use the
new Point() constructor to create a Point
Creates a new point. If you pass no parameters to this method, a point is created at(0,0).
The horizontal coordinate.
The vertical coordinate.
The length of the line segment from(0,0) to this point.
The horizontal coordinate of the point. The default value is 0.
The vertical coordinate of the point. The default value is 0.
Creates a copy of this Point object.
The new Point object.
Determines whether two points are equal. Two points are equal if they have the same x and y values.
The point to be compared.
A value of
true if the object is equal to this Point
false if it is not equal.
Scales the line segment between(0,0) and the current point to a set length.
The scaling value. For example, if the current point is (0,5), and you normalize it to 1, the point returned is at(0,1).
The normalized point.
Offsets the Point object by the specified amount. The value of
dx is added to the original value of x to create the
new x value. The value of
dy is added to the original
value of y to create the new y value.
The amount by which to offset the horizontal coordinate, x.
The amount by which to offset the vertical coordinate, y.
Returns a string that contains the values of the x and y
coordinates. The string has the form
y=_y_)", so calling the
toString() method for a
point at 23,17 would return
The string representation of the coordinates.
Determines a point between two specified points. The parameter
f determines where the new interpolated point is located
relative to the two end points specified by parameters
pt2. The closer the value of the parameter
1.0, the closer the interpolated point is to the first
pt1). The closer the value of the parameter
f is to 0, the closer the interpolated point is to the second
The first point.
The second point.
The level of interpolation between the two points. Indicates
where the new point will be, along the line between
pt1 is returned; if
pt2 is returned.
The new, interpolated point.
Converts a pair of polar coordinates to a Cartesian point coordinate.
The length coordinate of the polar pair.
The angle, in radians, of the polar pair.
The Cartesian point.
