public class Vector2D
extends Object

Implements a two dimensional (magnitude and direction) vector for physics calculations and provides a method for summing vectors.

Constructor Summary

Vector2D(float magnitude, float directionDegrees)
Constructs a Vector2D object.

Vector2D(Vector2D[] vectors)
Constructs a Vector2D object that is the sum of a set of vectors.

Method Summary

Vector2D	add(Vector2D vector) Adds a vector to this vector and returns a new Vector2D object containing the result.
float	getDirection() Gets the direction of the vector.
float	getMagnitude() Gets the magnitude of the vector.
void	setDirection(float directionDegrees) Sets the direction component of the vector.
void	setMagnitude(float magnitude) Sets the magnitude of the vector.
String	toString() Returns a String object containing the magnitude and direction (in degrees) of the vector in the format: magnitude, direction
