Question

Using the input file I have already downloaded (sprocketorders.txt), write a Java program to summarize the data from the input file and output a report. The report should appear in the output window when the program runs. I would like to use switch structure to solve this but if not, using a series of if-then statements would suffice.

The output report needs to look like this:

Spacely Sprockets

Taking Sprockets into the Future

Sales Summary Report

Sprocket Number   Total Quantity Sold

1 90

2 155

3 50

4 300

5 100

The data in the txt file appears as such:

3   50
2   20
2   100
5   15
1   90
5   85
4   300
2   35
3   100

Explanation / Answer

import java.util.*;
import java.io.*;
public class report
{
public static void main(String[] args) throws FileNotFoundException
{
Scanner in = new Scanner(new File("sprocketorders.txt"));
int[] array = new int[5];
for(int i=0; i<array.length; i++)
array[i] = 0;
    while(in.hasNext())
   {
   int num = in.nextInt();
   int Qty = in.nextInt();
   array[num-1] += Qty;
   }
System.out.println("Spacely Sprockets");
System.out.println("Taking Sprockets into the Future");
System.out.println("Sales Summary Report");
System.out.println("Sprocket Number   Total Quantity Sold");
for(int i=0; i<array.length; i++)
System.out.println(" "+(i+1) + " " + array[i]);
}
}
