Question

ASSIGNMENT: Write a program and use the attached file (babynames.txt) as input file, and create two output tiles. One file listing out all boys names, and the other file listing out all girls name.

CODE: (teacher gave some of the code below use it to find the answer please String B is the boy names String E is girl names)

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;

/**
This program reads a file with numbers, and writes the numbers to another
file, lined up in a column and followed by their total.
*/
public class Total
{
public static void main(String[] args) throws FileNotFoundException
{
// Prompt for the input and output file names

Scanner console = new Scanner(System.in);
System.out.print("Input file: ");
String inputFileName = console.next();
System.out.print("Output file1: ");
String outputFileName1 = console.next();
System.out.print("Output file2: ");
String outputFileName2 = console.next();

// Construct the Scanner and PrintWriter objects for reading and writing

File inputFile = new File(inputFileName);
Scanner in = new Scanner("babynames.txt");
PrintWriter out1 = new PrintWriter("boysnames.txt");
PrintWriter out2 = new PrintWriter("girlsnames.txt");

// Read the input and write the output

double total = 0;
  
  
while (in.hasNextLine())
{
String A = in.next();
String B = in.next();
String C = in.next();
String D = in.next();
String E = in.next();
String F = in.next();
String G = in.next();


out.printf("%15.2f\n", value);
total = total + value;
}

out.printf("Total: %8.2f\n", total);

in.close();
out.close();
  
}
}
