Problem 1 (name this Lab9_Problem1)

Create a new Notepad text file.

Populate it with these values, separated by a space, each line as shown:

10 5 4 11
15 33 2 -2
4 8 7 36

Save the file as 9_1_Input.txt in your c:homestudentlastname folder

Write a Java class with only a main() method.

Open the file for reading and traverses it through the end using a while loop based on the .hasNextInt() method. Hard-code the filename into your program.

Declare these variables. It will be up to you to manage them at the appropriate place in your program:
int iVal; // To capture each individual token as it's read from file
int iRow; // A total number of rows counter; initialize it to 0
int iRowSum; // A row sum accumulator variable
int iToken; // The counter variable for a for loop

Instantiate your file Scanner object as ifsInput.

Use a for loop structure to traverse each row and sum the values to a row total.

Display the row total as follows:

Row 1 sum: 30
Row 2 sum: 48
Row 3 sum: 55

Explanation / Answer

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

public class planeTicket {

private static Scanner ifsInput;

private static Scanner line;

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

       line = new Scanner(new File("9_1_Input.txt"));

       int iVal; // To capture each individual token as it's read from file

       int iRow = 0; // A total number of rows counter; initialize it to 0

       int iRowSum; // A row sum accumulator variable

       int iToken; // The counter variable for a for loop

       while (line.hasNext()) {

           ifsInput = new Scanner(line.nextLine());

           iRow++;

           iRowSum=0;

           while (ifsInput.hasNextInt()) {

               iVal = ifsInput.nextInt();

               iRowSum = iRowSum + iVal;

           }

           System.out.println("Row "+(iRow)+" sum: "+iRowSum);

       }

   }

}
