public class Point { Create two variables: 1. Generic Variable: Variable Name: data 2. Generic Point: Varibale Namе: пеxt Constructor that takes in two parameters (see above comment) wwm Setters and getters www tostring: output should be in the format: (data)-->(next) Example: Point p1,p2; p1.data = 4; p1.next = p2; p1.toString() would be: (4)--> (p2)
