`java.lang.Object`

`java.awt.geom.Point2D`

`java.awt.Point`

**Implemented Interfaces:**- Cloneable, Serializable

This class represents a point on the screen using cartesian coordinates.
Remember that in screen coordinates, increasing x values go from left to
right, and increasing y values go from top to bottom.

There are some public fields; if you mess with them in an inconsistent manner, it is your own fault when you get invalid results. Also, this class is not threadsafe.

**Since:**- 1.0

**See Also:**- Serialized Form

## Constructor Summary

`Point()`

- Initializes a new instance of
`Point`

representing the coordinates (0, 0).

`Point(int x, int y)`

- Initializes a new instance of
`Point`

with the specified coordinates.

`boolean`

`Point`

`getLocation()`

- Returns the location of this point.

`double`

`getX()`

- Get the x coordinate.

`double`

- Get the y coordinate.

`void`

`move(int x, int y)`

- Sets this object's coordinates to the specified values.

`void`

- Returns a string representation of this object.

`void`

`translate(int dx, int dy)`

- Changes the coordinates of this point such that the specified
`dx`

parameter is added to the existing X coordinate and`dy`

is added to the existing Y coordinate.

public Point()

Initializes a new instance of`Point`

representing the coordinates (0, 0).

Since:- 1.1

public Point(int x, int y)

Initializes a new instance of`Point`

with the specified coordinates.

Parameters:`x`

- the X coordinate`y`

- the Y coordinate

public Point(Point p)

Initializes a new instance of`Point`

with coordinates identical to the coordinates of the specified point.

Parameters:`p`

- the point to copy the coordinates from

Throws:`NullPointerException`

- if p is null

public boolean equals(Object obj)

Tests whether or not this object is equal to the specified object. This will be true if and only if the specified object is an instance of Point2D and has the same X and Y coordinates.

Parameters:`obj`

- the object to test against for equality

Returns:- true if the specified object is equal

public Point getLocation()

Returns the location of this point. A pretty useless method, as this is already a point.

Returns:- a copy of this point

Since:- 1.1

See Also:`setLocation(Point)`

public void move(int x, int y)

Sets this object's coordinates to the specified values. This method is identical to the`setLocation(int, int)`

method.

Parameters:`x`

- the new X coordinate`y`

- the new Y coordinate

public void setLocation(double x, double y)

Sets this object's coordinates to the specified values. This method rounds to the nearest integer coordinates by adding 0.5 and calling`Math.floor(double)`

.

Overrides:- setLocation in interface Point2D

Parameters:`x`

- the new X coordinate`y`

- the new Y coordinate

public void setLocation(int x, int y)

Sets this object's coordinates to the specified values. This method is identical to the`move()`

method.

Parameters:`x`

- the new X coordinate`y`

- the new Y coordinate

public void setLocation(Point p)

Sets this object's coordinates to match those of the specified point.

Parameters:`p`

- the point to copy the coordinates from

Throws:`NullPointerException`

- if p is null

Since:- 1.1

public String toString()

Returns a string representation of this object. The format is:`getClass().getName() + "[x=" + x + ",y=" + y + ']'`

.

Returns:- a string representation of this object

public void translate(int dx, int dy)

Changes the coordinates of this point such that the specified`dx`

parameter is added to the existing X coordinate and`dy`

is added to the existing Y coordinate.

Parameters:`dx`

- the amount to add to the X coordinate`dy`

- the amount to add to the Y coordinate
