The while loop makes multiple attempts to read a nonnegative integer from input into userAge. Use multiple exception handlers to: . Catch an Input MismatchException, output "Unexpected input: The UserAge program quits", and assign retry with false. • Catch an Exception and output the message of the Exception. End each output with a newline. Ex: If the input is 44, then the output is: Valid input: User's age is 44 Ex: If the input is L, then the output is: Unexpected input: The UserAge program quits Ex: If the input is -65 44, then the output is: User's age must be nonnegative Valid input: User's age is 44 11 12 13 14 15 16 17 18 19 20 21 ततततत & S 22 23 24 25 222 26 27} } try { userAge = scnr.nextInt (); if (userAge < 0) { throw new Exception ("User's age must be nonnegative"); } retry= false; System.out.print("Valid input: "); System.out.println("User's age is + userAge); } /* Your code goes here */ H

You can plot shapes in Python using line graphs in matplot lib by providing the coordinates of the vertices of the shapes as x, y pairs and using the matplotlib.pyplot.plot (i.e. plt.plot) function. Draw a triangle, square, pentagon, hexagon and heptagon. Note: Use symmetry, starting with the origin at (0,0), and set the distance from the origin to the vertex to be of length 1.0 (otherwise this becomes very complicated for some shapes).

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…

Write a program that draws a fixed polygonwith points at (30, 10), (60, 30), (50, 70), (35, 35), and (10, 50). Wheneverthe mouse is moved, display a message indicating whether the mousepoint is inside the polygon at the mouse point or outside of it, as shown inFigure. To detect whether a point is inside a polygon, use the containsmethod defined in the Node class.
