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).

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
