Constructs and initializes a point at the specified (x, y) location in the coordinate space.

Parameters:

x - the x coordinate.

y - the y coordinate.

Method Detail

hashCode

public int hashCode()

Returns a hashcode for this Double.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

equals

public boolean equals(java.lang.Object obj)

Compares this object against the specified object. The result is true if and only if the argument is not null and is a DoublePoint object such that the respective components are equal according to the rules of Double.equal().

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

toString

public java.lang.String toString()

Returns a String representation of this DoublePoint object.

Overrides:
