Constructor Detail

### Point2d

`public Point2d()`
Constructs and initializes a Point2d to (0,0).

### Point2d

`public Point2d(double[] p)`
Constructs and initializes a Point2d from the specified array.

Parameters:
`p` - the array of length 2 containing xy in order

### Point2d

```public Point2d(double x,
double y)```
Constructs and initializes a Point2d from the specified xy coordinates.

Parameters:
`x` - the x coordinate
`y` - the y coordinate

### Point2d

`public Point2d(Point2d p1)`
Constructs and initializes a Point2d from the specified Point2d.

Parameters:
`p1` - the Point2d containing the initialization x y data

### Point2d

`public Point2d(Point2f p1)`
Constructs and initializes a Point2d from the specified Point2f.

Parameters:
`p1` - the Point2f containing the initialization x y data

Method Detail

### clone

`public java.lang.Object clone()`
Specified by:
`clone` in class `Tuple2d`

### distance

`public final double distance(Point2d p1)`
Computes the distance between this point and point p1.

Parameters:
`p1` - the other point
