$*$ WITH COMMENTS PLEASE!$*$

In this assignment, you are asked to complete a Java program that converts a file format

to another. It should support the following formats:

$.$ ssv $($comma separated values$)$ file: stores tabular data in plain text. Each line of the

file represents a table row containing one or more cells separated by commas. If a

content of a cell has one or more commas $($e$.$g$.12,345),$ then that cell's content needs

to be enclosed in double$-$quotations $($e$.$g$."12,345").$

trt $($tab separated values$)$ file: stores tabular data in plain text. Each line of the file

represents a table row containing one or more cells separated by tab characters $(\frac{\frac{?}{?}}{t}).$

The content of each cell does not have any tab character.

$1$ Program Commands

$(35$ points$)$ convert

source.xxx destination.yyy: this command converts

source.xxx

to destination.yyy where

source.xxx is the name and extension of the file that user

wants to convert and destination.yyy is the name and extension of the file in which

the user wants to store the result of format conversion. Please note that $x$ and yyy

can either be csv or txt$.$ Also, the file names may or may not include the path to the

file in the file system.

$(60$ points$)$ normalize

source.xxx: this command reads the content of

source.xxx$,$

normalizes the content of each cell, and writes the normalized content back to the same

file. Normalizing a cell is an operation that depends on the current content of the cell:

if cell is empty: writes $\frac{N}{A}$ instead

if cell contains an integer: normalization explicitly shows the sign $(+$ for pos$-$

itive and $-$ for negative$).$ Also, if the integer representation is shorter than $10$

characters, it adds some leading zeros to make the representation $10$ character

long.

if cell contains a float$/$double: normalization shows two digit after decimal point.

Also, it uses scientific notation if the number is greater than $100$ or less than $0\mathrm{.}01.$

if cell contains a string longer than $13$ characters, normalization shows the first

$10$ characters of the string followed by an ellipsis $($three dots like this $...)$

otherwise, normalization causes no change.

$(5$ points$)$ quit: ends the program.
