FILL IN MISSING CODE in the specified areas to achieve the Sample Program Dialogue. (or close to it)
TAKE SCREENSHOT OF THE Compiled Output.
Add a private Random object named r to the ProblemX2 class
Validate the value of x using two assert-statements, (1) check condition #1 (1 assertion; and (2) separately check condition #2 (x
Add a personalized version of lines 9-26 of Figure 11.6 (shown below) to the body of the MyStackTrace() method.
