Question

Write a very small Java program that consist of:

1. A single class named Asn1BApp. Save the definition of this class in a file named Asn1BApp.java

2. The single class Asn1BApp should contain only the main method, and should read a file of numbers (of type double) from a file named asn1b.in. Should write the sum of those numbers (with appropriate label) and average of those numbers (with appropriate label). The sum and average should be displayed using 2 decimal points.

3. All output should be written to a file named asn1b.out. Use Scanner class for input and PrintWriter class for output.

4. No packages.

Please see the provided linked example files:

Explanation / Answer

import java.io.*;

import java.util.*;

public class Asn1BApp {

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

Scanner inputFile;

PrintWriter outputFile;

double value;

inputFile = new Scanner (new FileReader("C:\Users\Dhanraj Purbiya\Documents\NetBeansProjects\train\src\chegg\asn1b.dat"));

outputFile = new PrintWriter("C:\Users\Dhanraj Purbiya\Documents\NetBeansProjects\train\src\chegg\asn1b.out");

int i = 0; // index into fabricArray

value=0;

while (inputFile.hasNext()) {

value = value+inputFile.nextDouble();

i++;

}

inputFile.close();

Double average=value/i;

outputFile.println("Sum of all number is: "

+ value+" ");

outputFile.println("Average of all numbers is "

+ average);

outputFile.close();

} // end main

}
