| Field Summary | |
| public int | x
The x coordinate. | | public int | y
The y coordinate. |
| Constructor Summary | |
| public | Point()
Constructs and initializes a point at the origin
(0, 0) of the coordinate space. | | public | Point(Point p)
Constructs and initializes a point with the same location as
the specified Point object. | | public | Point(int x, int y)
Constructs and initializes a point at the specified
(x, y) location in the coordinate space. |
| Method Summary | |
| public Object | clone()
Creates a new object of the same class and with the
same contents as this object. | | public boolean | equals(Object obj)
Determines whether two points are equal. | | public Point | getLocation()
Returns the location of this point. | | public int | hashCode()
Returns the hashcode for this point. | | public void | move(int x, int y)
Moves this point to the specificed location in the
(x, y) coordinate plane. | | public void | setLocation(Point p)
Sets the location of the point to the specificed location. | | public void | setLocation(int x, int y)
Changes the point to have the specificed location. | | public String | toString()
Returns a representation of this point and its location
in the (x, y) coordinate space as a string. | | public void | translate(int x, int y)
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). |
| x | | public int x(Code) | | The x coordinate.

| y | | public int y(Code) | | The y coordinate.

| Point | | public Point()(Code) | | Constructs and initializes a point at the origin
(0, 0) of the coordinate space.
Parameters:
x - the x coordinate.
Parameters:
y - the y coordinate.
since:
JDK1.1 |
| Point | | public Point(Point p)(Code) | | 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)(Code) | | Constructs and initializes a point at the specified
(x, y) location in the coordinate space.
Parameters:
x - the x coordinate.
Parameters:
y - the y coordinate.
since:
JDK1.0 |
| clone | | public Object clone()(Code) | | Creates a new object of the same class and with the
same contents as this object.
a clone of this instance.
exception:
OutOfMemoryError - if there is not enough memory.

| equals | | public boolean equals(Object obj)(Code) | | Determines whether two points are equal. Two instances of
Point are equal if the values of their
x and y member fields, representing
their position in the coordinate space, are the same.
Parameters:
obj - an object to be compared with this point. true if the object to be compared isan instance of Point and hasthe same values; false otherwise.
since:
JDK1.0 |
| hashCode | | public int hashCode()(Code) | | Returns the hashcode for this point.
a hash code for this point.
since:
JDK1.0 |
| move | | public void move(int x, int y)(Code) | | Moves this point to the specificed location in the
(x, y) coordinate plane. This method
is identical with setLocation(int, int).
Parameters:
x - the x coordinate of the new location.
Parameters:
y - the y coordinate of the new location.

| toString | | public String toString()(Code) | | Returns a representation of this point and its location
in the (x, y) coordinate space as a string.
a string representation of this point, including the values of its member fields.
since:
JDK1.0 |
| translate | | public void translate(int x, int y)(Code) | | 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.
Parameters:
dy - the distance to move this point along the y axis.
