All Implemented Interfaces:

Serializable, Cloneable

A point representing a location in (x,y) coordinate space, specified in integer precision.

Since:

1.0

• Serialized Form

• Nested Class Summary
• Field Summary

  Fields

  int

  The X coordinate of this Point.

  int

  The Y coordinate of this Point.

• Constructor Summary

  Constructors

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

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

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

• Method Summary

  boolean

  Determines whether or not two points are equal.

  Returns the location of this point.

  double

  Returns the X coordinate of this Point2D in double precision.

  double

  Returns the Y coordinate of this Point2D in double precision.

  void

  Moves this point to the specified location in the (x,y) coordinate plane.

  void

  Sets the location of this point to the specified double coordinates.

  void

  Changes the point to have the specified location.

  void

  Sets the location of the point to the specified location.

  Returns a string representation of this point and its location in the (x,y) coordinate space.

  void

  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).

• Field Details
  • x

    public int x

    The X coordinate of this Point. If no X coordinate is set it will default to 0.

    Since:

    1.0

    See Also:

    • getLocation()
    • move(int, int)

  • y

    public int y

    The Y coordinate of this Point. If no Y coordinate is set it will default to 0.

    Since:

    1.0

    • getLocation()
    • move(int, int)

• Constructor Details
  • Point

    public Point()

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

    Since:

    1.1

  • Point

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

    Parameters:

    p - a point

    Since:

    1.1

  • 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 of the newly constructed Point

    y - the Y coordinate of the newly constructed Point

    Since:

    1.0

• Method Details
  • getX

    public double getX()

    Returns the X coordinate of this Point2D in double precision.

    Specified by:

    getX in class Point2D

    Returns:

    the X coordinate of this Point2D.

    Since:

    1.2

  • getY

    public double getY()

    Returns the Y coordinate of this Point2D in double precision.

    Specified by:

    getY in class Point2D

    Returns:

    the Y coordinate of this Point2D.

    Since:

    1.2

  • 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:

    1.1

    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:

    1.1

    See Also:

    • Component.setLocation(java.awt.Point)
    • getLocation()

  • setLocation

    public void setLocation(int x, int y)

    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:

    1.1

    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 or not two points are equal. 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 Point2D

    Returns:

    true if the object to be compared is an instance of Point2D and has the same values; false otherwise.

    See Also:

    • Object.hashCode()
    • HashMap

  • 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
