Define a class named point with two data fields x and y to represent a point’s x- and y-coordinates. implement the comparable interface for comparing the points on x-coordinates. if two points have the same x-coordinates, compare their y-coordinates. define a class named comparey that implements comparator . implement the compare method to compare two points on their  y-coordinates. if two points have the same y-coordinates, compare their x-coordinates. randomly create severl points or prompt the user for points. apply the arrays. sort method to display the points in increasing order of their x-coordinates and in increasing order of their y-coordinates, respectively.

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below
