In mathematics, a vector possesses a definite initial point and terminal point. Write a class called Vector that will represent a 2D vector with the initial point at the origin of the coordinate system. Your class should follow this specification It has two fields: terminal point coordinates Terminal point coordinates can only be set once via class constructor(s). You can assume terminal point coordinates are of type int, If terminal point coordinates are not specified, set both to zero, There are five accessor methods: getStartPointX(), getStartPointY(), getEndPointx(), getEndPointY(), getLength() which calculates and returns vector length, There are no mutator functions.

Now, using inheritance, create another class called BoundVector, that will also allow to specify vector initial point coordinates (for Vector class it was (0, 0)). Your second class should follow the following specification: It has four fields: initial and terminal point coordinates, Create constructors: No-argument constructor, Only terminal point constructor, Initial and terminal point constructor, Modify/override superclass methods that need to change, if any.
