Kindly help to check if the attached fulfills the instruction below. I sincerely welcome your corrections and advice on this. Now, change the main() routine so that it creates an AdditionProblem, displays to the user the problem returned by the getProblem() method, reads an answer from the user, and checks to see whether the answer entered by the user agrees with the correct answer as returned by getAnswer(). (It's a good idea to complete this little exercise if you want to use classes like this one in your real math quiz program; doing the exercise will make sure that you know how to use the class.)

* TextIO provides a set of static methods for reading and writing text. By default, it rea
* from standard input and writes to standard output, but it is possible to redirect the inp
* and output to files or to other input and output streams. When the standard input and ou
* streams are being used, the input methods will not produce an error; instead, the user is
* repeatedly prompted for input until a legal input is entered. (If standard input has bee
* changed externally, as by file redirection on the command line, this is not a reasonable
behavior; to handle this case, TextIO will give up after 10 consecutive illegal inputs an
* will throw an IllegalArgumentException.) For the most part, any other
* error will be translated into an IllegalArguementException.
* <p>For writing to standard output, the output methods in this class pretty much
* duplicate the functionality of System.out, and System.out can be used interchangeably wit
* <p>This class does not use optimal Java programming practices. It is designed specifical
* usable even by a beginning programmer who has not yet learned about objects and exception
* everything is in a single source file that compiles into a single class file, all the met
* static methods, and none of the methods throw exceptions that would require try...catch s
Also for this reason, all exceptions are converted into IllegalArgumentExceptions, even w
exception type doesn't really make sense.
