getLocation(),move(int, int)
-
y
public int y
The Y coordinate of thisPoint. If no Y coordinate is set it will default to 0.- Since:

Point
public Point()
Constructs and initializes a point at the origin (0, 0) of the coordinate space.- Since:
- 1.1
-
Point
public Point(Point p)
Constructs and initializes a point with the same location as the specifiedPointobject.- 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 constructedPointy- the Y coordinate of the newly constructedPoint- Since:
- 1.0

Method Detail
-
getX
public double getX()
Returns the X coordinate of thisPoint2Dindoubleprecision.
-
getY
public double getY()
Returns the Y coordinate of thisPoint2Dindoubleprecision.
-
getLocation
public Point getLocation()
Returns the location of this point. This method is included for completeness, to parallel thegetLocationmethod ofComponent.- 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 thesetLocationmethod ofComponent.- 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)Changes the point to have the specified location.This method is included for completeness, to parallel the
setLocationmethod ofComponent. Its behavior is identical withmove(int, int).- Parameters:
x- the X coordinate of the new locationy- 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 thanInteger.MIN_VALUEwill be reset toMIN_VALUE, and any number larger thanInteger.MAX_VALUEwill be reset toMAX_VALUE.- Specified by:
setLocationin classPoint2D- Parameters:
x- the X coordinate of the new locationy- 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 withsetLocation(int, int).- Parameters:
x- the X coordinate of the new locationy- 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), bydxalong thexaxis anddyalong theyaxis so that it now represents the point(x+dx,y+dy).- Parameters:
dx- the distance to move this point along the X axisdy- 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 ofPoint2Dare equal if the values of theirxandymember fields, representing their position in the coordinate space, are the same.- Overrides:
equalsin classPoint2D- Parameters:
obj- an object to be compared with thisPoint2D- Returns:
trueif the object to be compared is an instance ofPoint2Dand has the same values;falseotherwise.- See Also:
Object.hashCode(),HashMap
-
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 benull.
