The application should randomly select a circle diameter in the range from 5 to 199, inclusive. To draw a blue circle with a given diameter (diameter), use the fol- lowing statement:
The drawOval method draws the outline of an oval. Recall that an oval is a circle if the height and width arguments are the same (in this case, the randomly selected width and height). Use the x- and y-coordinates of the mousePressed event as the x- and y-coordi- nates of the circle’s bounding box (that is, the first and second arguments to the drawOval method).
a) Copying the template to your working directory. Copy the C:Examples Tutorial21ExercisesCirclePainter directory to your C:SimplyJava direc- tory.
b) Opening the template file. Open the DrawJPanel.java file in your text editor.
c) Coding the drawJPanelMousePressed method. Find the drawJPanelMousePressed method, which starts at line 58. Add code to the drawJPanelMousePressed method to store the x- coordinate in instance variable x (declared for you in the template) and store the y- coordinate in instance variable y (declared for you in the template), Then, store a random int in the range 5 to 199 into the inst
