Constructor Detail

Point

public Point(int x,
     int y)

Initializes this point with the given x- and y-coordinate.

Parameters:

x - the x-coordinate of this point.

y - the y-coordinate of this point.

Method Detail

hashCode

public int hashCode()

Returns the hash code of this point.

Overrides:

hashCode in class Object

Returns:

the hash code of this point.

equals

public boolean equals(Object object)

Tests whether this point is the same as the given object. Two points are the same if they have the same x- and y-coordinates.

Overrides:

equals in class Object

Parameters:

object - an object

Returns:

true if this point is the same as the given object, false otherwise.

compareTo

public int compareTo(Point other)

Compares this point to the other given point. Returns a negative integer/zero/positive integer if this point is smaller than/the same/greater than the other point in the lexicographic order.

Specified by:

compareTo in interface Comparable<Point>

Parameters:

other - another point.

Returns:

a negative integer/zero/positive integer if this point is smaller than/the same/greater than the other point in the lexicographic order.

toString

public String toString()

Returns a string representation of this point. The representation is of the form (x, y), where x and y are the x- and y-coordinates of this point.

Overrides:

toString in class Object

Returns:

a string representation of this point.
