Compare and contrast the linear search and binary search algorithms by searching for the numbers 45 and 54 in the following list:

3 8 12 34 54 84 91 110


Searching for 45, which isn't in the list, requires eight comparisons in a linear search to exhaust all possibilities, whereas a binary search will determine that the target is not in the list after three comparisons. A linear search will find the value 54 in the list in five comparisons, and a binary search finds it in three comparisons.

Which of the following statements is false?

a. When the user interacts with a GUI component, the interaction—known as an event—drives the program to perform a task. b. For events that occur when the value of a control’s property changes, you must create the event handler entirely using only drag and drop in Scene Builder. c. The code that performs a task in response to an event is called an event handler. d. For certain events you can link a control to its event-handling method by using the Code section of Scene Builder’s Inspector window. In this case, the event-listener interface is implemented for you to call the method that you specify.
