Program Plan Intro

Program to create the polygon through convex hull animation

Program Plan:

  • Import the required java packages.
  • Create the class named “Exercise22_13”,
  • In the main() function,
    • Declare the class “View” to draw and fill the color of rectangles.
    • Raise the event inside the rectangle to set the event by right clicking or left clicking the mouse.
    • Call the function drawNewPolygon() to draw the polygon with the respective points.
  • In the drawNewPolygon() method,
    • Retrieve all the points from the array list.
    • Execute the for loop to add the points inside the circle.
    • Clear the polygon.
    • If the size of the points is greater than 3, then find out the centre position of the co-ordinates of “x” and “y” and call the function getConvexHull() to add the array list of points.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example, Letter 'h' Binary ASCII 01101000 68H 'H'…
