Data Structure & Algorithum java program Do the following: 1) Add a constructor to the class "LList" that creates a list from a given array of objects. 2) Add a method "addAll" to the "LList" class that adds an array of items to the end of the list. The header of the method is as follows, where "T" is the generic type of the objects in the list.

PLEASE CODE IN PYTHON  PLEASE USE NESTED CLASS FUNCTION   Design a Point Class with attributes X and Y coordinates. The Class should have following functions: a) change the coordinates, b) return a 2 element list [x,y] c) print a Point object. d) return distance from this instance to a given [x,y]   Also design a Line Class which has 2 Point attributes. The Line class should have functions for following behaviours: a) Return the length of the line. b) Print the equation of the line c) Find if this instance is equal in length to another line.
