Create a simple Java program similar to Linux tail command ([login to view URL])

Create a simple Java program similar to Linux tail command ([url removed, login to view])

1. Create a Simpletail command line program similar to Linux tail but with limited functionality. Linux tail manual is available at [url removed, login to view]

2. Simpletail must support at least the following functions:

- show last n lines of a file

- optional number of lines option

- help message

- error reporting in case of invalid parameter or file

Please note that live watch function (as in tail -f option) is not required.

For example:

>java -jar [url removed, login to view] -n 3 [url removed, login to view]

> return result;

> }

>}

>java -jar [url removed, login to view] –help

>usage: simpletail [-n lines] file

>java -jar [url removed, login to view] -n -1 [url removed, login to view]

>ERROR: invalid number of lines -n

3. Simpletail must be built as a standalone jar ([url removed, login to view]). Instructions must be provided and it

should be easy to build.

4. Simpletail must be reasonably optimized. For example, reading whole file into an array and extract

the tail is unacceptable.

Unit tests may be included.

5. Simpletail should contain a reusable tail API.

6. Simpletail should be able to handle Unix, Macintosh and Windows newlines.
