Question reference:Â Refer to Chapter 4 Exercise 4.85 to write the method, listAllFiles(), with the do-while loop rather than for-each loop.
Program Description Answer
Method Explanation:
The method, listAllFiles(), is used to show the list of all the files present.
Using a do-while loop instead of for each loop in the method listAllFiles.
It will not work if the collection is empty as do-while loop will run once, even at the wrong condition.

Complete the implementation of the LinkedStack class by providing the definitions for the peek, size, isEmpty, and toString methods.
Write out the header of a for-each loop to process an ArrayList called tracks. Don’t worry about the loop’s body.
tests the pop_back() method of thelink list container, clears the container with the clear() function, and uses theempty() method to test if the container is empty. When using the link list, it is veryimportant to call the empty() function instead of testing if size() returns the valueof 0. Although this might sound strange, it isn’t when working with link lists. Thefunction empty() is a constant-time operation that is normally implemented as aninline function, that is, very fast use c++ to code
