Vector class lab assignment

Resources

• MathIsFun - Vectors
• Converting from Polar to Cartesian

Vector class

• Create a Vector class using the following specifications (HINT: Use any of your notes or other classes as resources):

BE SURE TO COMMENT YOUR CODE

Attributes (private):

• double magnitude (default: 0)
• double direction (default: 0)

Methods (public)

• Vector() - default constructor
• Vector(double r, double theta) - specific constructor
• void setMag(double newMag)
• void setDir(double newDir)
• double getMag()
• double getDir()
• double getX()
  • returns the Cartesian x-coordinate of the Vector (look at Resources to convert Polar->Cartesian)
• double getY()
  • returns the Cartesian y-coordinate of the Vector (look at Resources to convert Polar->Cartesian)
• String toString() - returns a String representation of the Vector
• Vector add(Vector v)
  • returns a new Vector after calculating the Vector addition of itself and Vector v
• Vector sub(Vector v)
  • returns a new Vector after calculating the Vector subtraction of itself and Vector v

Testing your Vector class

• Write your own main method to test out all the methods in the Vector class
