Question

Your Java program will be reading input from a file name strInput.txt. Each record contains String firstname String lastName String strSalary (which will be converted to a double if it's valid- see below) char status String cityState (city and state and combine together but separated by a comma)
Sample input:
Ira Rudowsky 87654.32 F Brooklyn.NY
Jane Doe 987609.87 F NY NY
Mickey Mantle 345678.30 D Orlando FL
Fran Young 10456A.82 G Boston MA
Richard Clark 67890.32 D
Serena liams 1295609.87 D Denver, CO
Read from the file one record at a time and process as follows:
1. Any record whose status code is neither D or F should be written to the screen indicating the error. The next record should be read in
2. If the status code is D or F, validate the salary that it contains only digits and one decimal point 3 positions from the right (indicating cents)
a. If the salary is invalid, print the entire record to the screen, indicating the error (char at position x is not a digit or period is missing or period is in the wrong position)
b. If the salary is valid, convert it to a double c. If the status code is D, compute the bonus (double) as 12.5% of salary and 18% if the status code is F
3. Separate the cityState into two individual Strings named city and state. Use the comma to extract the city portion before the comma and the state after the comma
4. Each record that has a status of D should be written to a file named strOutputD and those record with status of F should be written to a file named strOutputRE.
a. For both files, each record printed should include firstName, lastName, status, salary, bonus, city and state
5. When all records have been read in, print to the screen the number of D, F and incorrect records processed

Answer 1

Answer:

The program requires that you have the specified input files and it reads from each file at a time and processes salary in digits, states the city, state and bonus with respective first and last name as requested in the question. Note that you must have access to the mentioned output files for the program to work properly. Below is the java version of the program.

import java.io.File;

import java.io.FileNotFoundException;

import java.io.PrintWriter;

import java.util.Scanner;

class Driver

{

public static void main(String[] args) throws FileNotFoundException

{

Scanner sc = new Scanner(new File("strInput.txt"));

PrintWriter pd = new PrintWriter(new File("strOutputD"));

PrintWriter prf = new PrintWriter(new File("strOutputRF"));

String firstname = "", lastname = "", strSalary = "", status = "", cityState = "", city = "", state = "";

double salary = 0, bonus = 0;

int incorrectRecords = 0;

int dRecords = 0;

int fRecords = 0;

while(sc.hasNextLine())

{

firstname = sc.next();

lastname = sc.next();

strSalary = sc.next();

status = sc.next();

cityState = sc.next();

if(!status.equals("D") && !status.equals("F"))

{

System.out.println("Records is neither D nor F. Skipping this...");

incorrectRecords++;

continue;

}

else if(status.equals("D") || status.equals("F"))

{

char c = ' ';

int i = 0;

for(i=0; i<strSalary.length() && c != '.'; i++)

{

c = strSalary.charAt(i);

if(!Character.isDigit(c))

{

System.out.println("Char at position " + (i+1) + " in salary is not a digit");

incorrectRecords++;

continue;

}

}

if(c == '.')

{

if(i+1 == strSalary.length()-1)

{

if(!Character.isDigit(strSalary.charAt(i)))

{

System.out.println("Char at position " + (i+1) + " in salary is not a digit");

incorrectRecords++;

continue;

}

if(!Character.isDigit(strSalary.charAt(i+1)))

{

System.out.println("Char at position " + (i+1+1) + " in salary is not a digit");

incorrectRecords++;

continue;

}

}

else

{

System.out.println("Period is in the wrong position. Expected at " + (strSalary.length()-3) + " but found at " + (i+1));

continue;

}

}

city = cityState.split(",")[0];

state = cityState.split(",")[1];

salary = Double.parseDouble(strSalary);

if(status.equals("D"))

{

bonus = salary * 0.125;

dRecords++;

pd.write(firstname + " " + lastname + " " + status + " " + salary + " " + bonus + " " + city + " " + state);

}

else

{

bonus = salary * 0.18;

fRecords++;

prf.write(firstname + " " + lastname + " " + status + " " + salary + " " + bonus + " " + city + " " + state);

}

}

}

System.out.println("No of D records : " + dRecords);

System.out.println("No of F records : " + fRecords);

System.out.println("No of incorrect records : " + incorrectRecords);

}

}
