Explanation:
Java code:
//Header file section
import java.util.Scanner;
import java.io.*;
//main class
public class SalesTestDemo
{
//main method
public static void main(String[] args) throws IOException
{
String inFile;
String line;
double total = 0;
Scanner scn = new Scanner(System.in);
//Read input file name
System.out.print("Enter input file Name: ");
inFile = scn.nextLine();
FileReader fr = new FileReader(new File(inFile));
BufferedReader br = new BufferedReader(fr);
System.out.println("Name \t\tService_Sold \tAmount \tEvent Date");
System.out.println("=====================================================");
line = br.readLine();
//Each line contains the following, separated by semicolons:
//The name of the client, the service sold
//(such as Dinner, Conference, Lodging, and so on)
while(line != null)
{
String temp[] = line.split(";");
for(int i = 0; i < temp.length; i++)
{
System.out.print(temp[i]+"\t");
if(i == 1)
System.out.print("\t");
}
//Calculate total amount for each service category
total += Double.parseDouble(temp[2]);
System.out.println();
line = br.readLine();
}
//Display total amount
System.out.println("\nTotal amount for each service category: "+total);
}
}
