Download as DOCX, PDF0 likes7 views
The document is a programming task that requires writing a Java program to read user input strings and write them to a file named userstrings.txt, stopping when the user inputs 'done'. The program should not include the sentinel string 'done' in the output file. A brief code snippet illustrates the main logic and error handling for file operations.

Q2: Write a program that reads strings from the user and writes them to an output file called
userStrings.txt. Stop processing when the user enters the string "DONE". Do not write the
sentinel string ("DONE") to the output file. [15 points] Hint: For a complete example of file IO,
please see the attached TestData program.
Sample Output:
A string.
Another string.
Yet more text...
DONE
Solution
