Point Part a: Write an immutable class called Point to represent a point on the two dimensional Cartesian plane, with the following variables and methods: 1. Private data fields: x of type double and y of type double; 2. Public constructor: only one constructor that takes a double x_coord and a double y_coord as arguments; 3. Public methods: boolean equals(Point anotherPoint): returns true if the invoking Point is equal to the argument Point. Two points are equal if they have the same x coordinate and the same y coordinate; boolean lessThan(Point anotherPoint): returns true if a Point is less than another Point by the following rule: first compare points by their ycoordinates, breaking ties by their x-coordinates and only if either yo
