JAVA HELP

4. (2 points) Write the missing constructor for the Polygon class below. Hint, you need to make sure each Polygon has its OWN array of Point and isnt sharing that array with another Polygon. You also need to make sure the points are not also shared between two arrays. Your code must work for any number of points, not just with 3 as shown in the example.

5. (2 points) Add the missing add() method to Polygon so that new points can be added as shown by the last 2 lines of main(). Your code should allow add() to be called multiple times to add multiple points. Do not use an ArrayList. Hint: you will need to make a new larger array and copy the values from the old array to the new larger array.

2. (3 points) Complete the figure to the right to show the contents of the memory and enter the output of the program in the large box. The figure has been started reflecting the memory after the completion of the first assignment to p2 (line 2 of main). Use the Point class showing on the screen. class PointTestP2 public static void main (String[] args) pl 9000 p2 9008 1000 1004 Point p1-new Point (22, 33) Point p2 = new Point (45, 67); mystery (pl) System.out.println (p1); p1 - new Point (17, 18) p2 = p1; p1.translate (200, 300) System.out.println (pl) System.out.println (p2) x 22 Y 33 x 45 y 67 9000 9004 9008 9012 9016 9020 9024 9028 static void mystery (Point p) p.translate (10,20) 3. (1 point) Write the missing method needed to proplery compare Point objects as shown in the example below. The missing method would be added to the Point class shown on the board class PointTestP3 public static void main (String[] args) int pl - new Point (5, 6) i Point p2 = new Point (5, 6); System.out.println (pl.equals (p2))/7 prints "true" ArrayList.
