A point represents an
coordinate.
x
public int x
- The x coordinate.
y
public int y
- The y coordinate.
Point
public Point(int x, int y)
- Constructs and initializes a point to the specified
coordinate.
- Parameters:
x
- the x coordinate
y
- the y coordinate
equals
public boolean equals(Object obj)
- The result is true if and only if the argument is not null and is a Point object
that has the same x and y coordinates as this object.
- Parameters:
obj
- the object to compare with.
- Returns:
- true if the objects are the same; false otherwise.
- Overrides:
- equals in class Object (I-§1.12.3).
hashCode
public int hashCode()
- Returns:
- a hash code value for this point.
- Overrides:
- hashCode in class Object (I-§1.12.6).
move
public void move(int x, int y)
- Modifies this point so that it now represents the
coordinates indicated.
- Parameters:
x
- the new x coordinate
y
- the new y coordinate
toString
public String toString()
- Returns:
- a string representation of this point.
- Overrides:
- toString in class Object (I-§1.12.9).
translate
public void translate(int dx, int dy)
- Translates this point by dx to the right and dy downward so that it now represents the point
, where it had been representing the
point
.
- Parameters:
dx
- the amount to move this point to the right
dy
- the amount to move this point downward
