Download and import the LabDocumentationGiven.zip project. Rename the project to:

sidd$4790\_$l$01$

This project contains a ScannerTest class and a Main class to test the ScannerTest class. Using the Scanner methods listed in the Java API documentation, alter the ScannerTest class to do the following:

Update the countLines method to count the number of lines in a file. The main method opens the source code file as a File object to use for testing:

File file $=$ new File$("$src$/$cp$213/$ScannerTest$.$java"$)$;

Scanner source $=$ new Scanner$($file$)$;

Note that Java looks for data files in the project's root folder. Note also that Java may wish to throw an Exception if the file cannot be found.

Update the countTokens method to count the number of tokens in the file. A token is anything that is surrounded on both sides by a space character $-$ a space, tab, end of line, or end of file$/$string$.$ Each word in this paragraph is a separate token.

Update the readNumbers method to quit only when a q is entered and to reject all other non$-$integers with the error message: not an integer $.$ Example:

$5$

$8$

what?

'what?$\text{'}$ is not an integer or $\text{'}$q$\text{'}.$

how about $7?$

'how about $7?\text{'}$ is not an integer or $\text{'}$q$\text{'}.$

$7$

q
