Field Detail

### x

    public int x

  The x coordinate. If no x coordinate is set it will default to 0.

  See Also:
    `getLocation()`, `move(int, int)`

### y

    public int y

  The y coordinate. If no y coordinate is set it will default to 0.

  See Also:
    `getLocation()`, `move(int, int)`

Constructor Detail

### Point

    public Point()

  Constructs and initializes a point at the origin (0, 0) of the coordinate space.

Since:
  JDK1.1

### Point

    public Point(Point p)

  Constructs and initializes a point with the same location as the specified `Point` object.

Parameters:
  `p` - a point
Since:
  JDK1.1

### Point

    public Point(int x,
                 int y)

  Constructs and initializes a point at the specified (x, y) location in the coordinate space.

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

Method Detail

### getX

    public double getX()

  Returns the X coordinate of the point in double precision.

  Specified by:
    `getX` in class `Point2D`
  Returns:
    the X coordinate of the point in double precision

### getY

    public double getY()

  Returns the Y coordinate of the point in double precision.

  Specified by:
    `getY` in class `Point2D`
  Returns:
    the Y coordinate of the point in double precision

### getLocation

    public Point getLocation()

  Returns the location of this point. This method is included for completeness, to parallel the `getLocation` method of `Component`.

  Returns:
    a copy of this point, at the same location
  Since:
    JDK1.1
  See Also:
    `Component.getLocation()`, `setLocation(java.awt.Point)`, `setLocation(int, int)`

### setLocation

    public void setLocation(Point p)

  Sets the location of the point to the specified location. This method is included for completeness, to parallel the `setLocation` method of `Component`.

  Parameters:
    `p` - a point, the new location for this point
  Since:
    JDK1.1
  See Also:
    `Component.setLocation(java.awt.Point)`, `getLocation()`

### setLocation

    public void setLocation(int x,
                            int y)

  Changes the point to have the specified location.

  This method is included for completeness, to parallel the `setLocation` method of `Component`. Its behavior is identical with `move(int, int)`.

  Parameters:
    `x` - the x coordinate of the new location
    `y` - the y coordinate of the new location
  Since:
    JDK1.1
  See Also:
    `Component.setLocation(int, int)`, `getLocation()`, `move(int, int)`

### setLocation

    public void setLocation(double x,
                            double y)

  Sets the location of this point to the specified double coordinates. The double values will be rounded to integer values. Any number smaller than `Integer.MIN_VALUE` will be reset to `MIN_VALUE`, and any number larger than `Integer.MAX_VALUE` will be reset to `MAX_VALUE`.

  Specified by:
    `setLocation` in class `Point2D`
  Parameters:
    `x` - the x coordinate of the new location
    `y` - the y coordinate of the new location
  See Also:
    `getLocation()`

### move

    public void move(int x,
                     int y)

  Moves this point to the specified location in the (x, y) coordinate plane. This method is identical with `setLocation(int, int)`.

  Parameters:
    `x` - the x coordinate of the new location
    `y` - the y coordinate of the new location
  See Also:
    `Component.setLocation(int, int)`

### translate

    public void translate(int dx,
                          int dy)

  Translates this point, at location (x, y), by `dx` along the x axis and `dy` along the y axis so that it now represents the point (`x` `+` `dx`, `y` `+` `dy`).

  Parameters:
    `dx` - the distance to move this point along the x axis
    `dy` - the distance to move this point along the y axis

### equals

    public boolean equals(Object obj)

  Determines whether an instance of `Point2D` is equal to this point. Two instances of `Point2D` are equal if the values of their `x` and `y` member fields, representing their position in the coordinate space, are the same.

  Overrides:
    `equals` in class `Point2D`
  Parameters:
    `obj` - an object to be compared with this point
  Returns:
    `true` if the object to be compared is an instance of `Point` and has the same values; `false` otherwise

### toString

    public String toString()

  Returns a string representation of this point and its location in the (x, y) coordinate space. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be `null`.

  Overrides:
    `toString` in class `Object`
  Returns:
    a string representation of this point
