In this assignment, you implement a program for storing the personal information of If the user enters information in a way that is not consistent with the mentioned format, your

program must gracefully handle the situation by printing a message on the screen asking the

user to partially$/$completely re$-$enter the information that was previously entered in a wrong

format.

$1\mathrm{.}2$ Data Structure, Interface and Classes

Your program must have an interface called "CSVPrintable" containing the following three

methods:

String getName $()$;

int getID $()$ ;

void csvPrintln $($ PrintWriter out$)$;

You need to have two classes called "Student" and "Teacher" implementing CSVPrintable

interface and another class called $"$TA$"$ extending Student class. Both Student and Teacher

classes must have appropriate variables to store Name and ID$.$

In order to store Phone, Student class must have a phone variable of type long that can

store a $10-$digit integer; while the Teacher class must have a phone variable of type int to

store only the $4-$digit postfix of the phone number.

Method getName has to be implemented by both Student and Teacher classes in the

same way. Class Student must implement getID in a way that it returns the StudentID

and ignores the TeacherID given by the input. Class Teacher must implement getID in a

way that it returns the TeacherID and ignores the StudentID given by the input. Class TA

must override the Student implementation of getID so that it returns the maximum value of

StudentID and TeacherID.

Method csvPrintln has to be implemented by Student and Teacher classes $($and overridden

by TA class$)$ so that it writes the following string followed by a new line on the output stream

out:

getName$()+,+$getID$()+,+$ phone

$1\mathrm{.}3$ Output $.$csv File

The program must store the personal information of students, teachers and TAs in a comma$-$

separated values $(.$csv$)$ file called "out.csv$".$ You need to construct the output file by repet$-$

itively calling the csvPrintln method of every CSVPrintable object instantiated in your

program. The output $.$csv file stores the information of every individual in a separate row;

while each column of the file stores different type of information regarding the students and

teachers $($i$.$e$.$ Name, ID and phone columns$).$ Please note that you should be able to open

the output file of your program using MS$-$Excel and view it as a table.

$2$ Sample Input$/$Output

Assume that the user enters the following four lines in console: Teacher Alex,Martinez $0987653053489999$

Student Rose,Gonzales $5678909876543210$

TA John,Cruz $88888999991234567890$

The program must write the following content in the out.csv file.

Alex Martinez, $98765,9999$

Rose Gonzales,$56789,9876543210$

John Cruz, $99999,1234567890$

$3$ Submissions

You need to submit a $.$zip file compressing the Java source file$($s$)$ of your program $(.$java

files$).$

students and teachers of a school in a comma$-$separated values $(.$csv$)$ file.

$1$ Problem Specification

In order to implement the system, you need to write a java program that gets the personal

information of individuals from the console and store it in different rows of the output $.$ csv

file.

$1\mathrm{.}1$ Input Format

User enters personal information of $n$ students and teachers using the console in the following

format:

$n$

Position ${?}_1$ Name ${?}_1$ StudentID ${?}_1$ TeacherID Phone ${?}_1$

Position ${?}_{2}Nam{e}_2$ StudentID $2$ TeacherID Phone ${?}_2$

Position ${?}_{3}Nam{e}_3$ StudentID $3$ TeacherID $3$ Phone ${?}_3$

$...$

Position ${?}_n$ Name ${?}_n$ StudentID ${?}_n$ TeacherID ${?}_n$ Phone ${?}_n$

Please note that the first line contains only an integer counting the number of lines

following the first line.

In each of the $n$ given input lines,

Position must be one of the following three strings "student", "teacher", or $"$TA$".$

Name must be a string of two words separated by a single comma only.

StudentID and TeacherID must be either $"0"$ or a string of $5$ digits. If Position is

"teacher", StudentID is zero, but TeacherID is not zero. If Position is "student",

TeacherID is zero, but StudentID is not zero. If Position is $"$TA$",$ neither StudentID

nor TeacherID are zero.

Phone is a string of $10$ digits.
