import java.util.Scanner;

public class ValidateCheckDigits {

public static void main(String[] args) {

String fileName = "numbers.txt"; //input file name

String validFileName = "valid_numbers.txt"; // file name of the output file

//Open the input file for reading and output file for writing

try(Scanner fileScanner = new Scanner( new File(fileName));

BufferedWriter fileWriter = new BufferedWriter( new FileWriter(validFileName))) {

//Until we have lines to be read in the input file

while(fileScanner.hasNextLine()) {

//Read each line

String line = fileScanner.nextLine().trim();

//calculate the sum of first 5 digits

int sum = 0;

for(int i = 0; i < 5; i++) {

sum += Integer.parseInt( line.charAt(i) + "");

}

//Get the last digit

int lastDigit = Integer.parseInt(line.charAt(5)+"");

//Check if the remainder of the sum when divided by 10 is equal to last digit

if(sum%10 == lastDigit) {

//write the number in each line

fileWriter.write(line);

fileWriter.newLine();

System.out.println("Writing valid number to file: " + line);

}

}

System.out.println("Verifying valid numbers completed.");

} catch(IOException ex ) {

System.err.println("Error: Unable to read or write to the file. Check if the input file exists in the same directory.");

}

}

}

The speed density fuel injection system uses the blank sensor as the primary sensor as the primary sensor to determine base puls
aivan3 [116]

Answer:

A) Map

Explanation:

All gasoline (petrol) fuel systems need ways or method that will be calculating amount of the air that is entering the engine.This is true as regards mechanical fuel injection, carburetors and electronic fuel injection.Speed density system fall under one of this method. "Speed" in this context means the speed of the engine while "density" means density of the air. The Speed is been measured using the distributor, crankshaft position sensor could be used here. The Density emerge from from measuring of the air pressure which is inside the induction system, using a typical "manifold absolute pressure" (MAP) sensor as well as air temperature sensor. Using pieces of information above, we can calculate

mass flow rate of air entering the engine as well as the correct amount of fuel can be supplied. With this system,

the mass of air can be calculated. One of the drawback if this system is that

Any modification will result to incorrect calculations. Speed-Density can be regarded as method use in estimation of airflow into an engine so that appropriate amount of fuel can be supplied as well as. adequate spark timing. The logic behind Speed-Density is to give prediction of the amount of air ingested by an engine accurately during the induction stroke. Then this information could now be used in calculating how much fuel is required to be provided, This information as well can be used in determining appropriate amount of ignition advance. It should be noted The speed density fuel injection system uses the Map sensor as the primary sensor to determine base pulse width
