Java Programming Quiz: Remote Control Project Review

What is the purpose of top-down design or stepwise refinement?

• To look at the big picture first and start breaking the overall problem down into smaller sub-systems

• To define and call methods in Java

• To work with numbers and strings

• To test the program for errors and bugs

What is the benefit of testing in isolation during the development process?

• It helps in working with numbers and strings

• It allows finding and fixing problems in small stages instead of debugging an entire program at once

• It helps in defining and calling methods in Java

• It ensures the program meets the original requirements

What are the important properties of a television that can be controlled with a remote?

• Channel and power status

• Volume and power status

• Power status and channel

• Channel and volume

What does the Remote object allow the user to do?

• Change the channel and adjust the volume

• Create a television schedule

• Turn the TV off and on

• Select a command and send it to a specific television

What does the Schedule class define?

• Properties to track the current power status, channel, and volume

• Methods for testing the Television class

• Static methods and properties for producing a description of the show currently streaming at a given day and time

• Public methods to turn the TV off and on, change the channel, and adjust the volume

What does the Television object manage?

• Properties to track the current power status, channel, and volume

• Methods for testing the Schedule class

• Static methods and properties for producing a description of the show currently streaming at a given day and time

• Public methods to turn the TV off and on, change the channel, and adjust the volume

What is the purpose of stepwise refinement in programming?

• To break the overall problem down into smaller and smaller sub-systems

• To define and call methods in Java

• To work with numbers and strings

• To test the program for errors and bugs

What does the RemoteTester class help with?

• Testing the Schedule and ensuring it works properly

• Testing the Television to verify that each method works correctly

• Creating a Television object and a Remote object

• Testing the Remote to ensure it works properly

What does the TelevisionTester class help with?

• Testing the Remote to ensure it works properly

• Creating a Television object and a Remote object

• Testing the Television to verify that each method works correctly

• Testing the Schedule and ensuring it works properly

What does the Main class at the end provide?

• The main() logic to launch the entire system

• The main() logic to test the Schedule and ensure it works properly

• The main() logic to test the Remote and ensure it works properly

• The main() logic to test the Television and ensure it works properly
