Modify the Total program so that it writes the values in two columns, like this:
Previous answer Chegg provided displayed the correct output for in.txt but now, how do I make
the empty blank as shown?
Previous solution provided by Chegg:
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;
public class Total {
public static void main(String[] args) throws FileNotFoundException {
Scanner console = new Scanner(System.in);
System.out.print("Input file: ");
String inputFileName = console.next();
String outputFileName = "out.txt";
File inputFile = new File(inputFileName);
Scanner in = new Scanner(inputFile);
PrintWriter out = new PrintWriter(outputFileName);
double total = 0;
while (in.hasNext()) {
double value1 = in.hasNextDouble() ? in.nextDouble() : 0;
double value2 = in.hasNextDouble() ? in.nextDouble() : 0;
out.printf("%8.2f %7.2f%n", value1, value2);
total += (value1 + value2);
}
out.printf("Total: %10.2f%n", total);
in.close();
out.close();
}
} Your file content Your program produced no output Expected file content
1: Compare output Output differs. See highlights below. Special character legend 2: Compare
output A Input in2.txt.
