Explanation of Solution
Given: The number-display project.
To find: The result after calling the object’s increment method until the value in the inspector rolls over to zero from the inspector window and record method calls from the Terminal window.
Solution:
Open number-display project.
In order to open Terminal window, it is necessary to click the Show Terminal from the View menu.
In order to record the method calls, it is necessary to click on the Options button and click Record method calls.
Now, compile the NumberDisplay class and then create an object.
Set the name of the instance as hours and the rollover limit as 24.
Now, open the object inspector window for the NumberDisplay object and then call the object’s increment method and observe the changes displayed in the Terminal window.

- PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.arrow_forwardOpen the clock-display project and create a ClockDisplay object by selecting the following constructor: new ClockDisplay() Call its getTime method to find out the initial time the clock has been set to.

- My code won't print out the desired test cases. For instance, the time and the event did not properly store it in the skiplistmap class, so it prints out none regardless of time and event. Also, when printing out the skiplist, it will just print out empty for each level regardless of the time and event being stored. So, can you take a look at my code and fix it?
