Field Detail

x

public int x

Class is disabled.

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

Class is disabled.

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 Detail

Point

public Point()

Class is disabled.

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

Since:

1.1

Point

public Point(Point p)

Class is disabled.

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)

Class is disabled.

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 Detail

getX

public double getX()

Class is disabled.

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()

Class is disabled.

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()

Class is disabled.

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)

Class is disabled.

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)

Class is disabled.

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:

1.1

See Also:

Component.setLocation(int, int), getLocation(), move(int, int)

setLocation

public void setLocation(double x,
                        double y)

Class is disabled.

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)

Class is disabled.

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)

Class is disabled.

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)

Class is disabled.

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.

Object.hashCode(), HashMap

toString

public String toString()

Class is disabled.

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
