So I need emergency help in writing a program that does a few simple things. I have a file that is composed of positive, negative and zero integers. Each integer has its own line and I'd say there's about 100 lines. I need help writing a program that will
1. Read the file and create and array from the data
2. Use that array to calculate the mode of the integers (the most frequently used integer)
3. Display the output back to the user.
Below I posted my current code using the hint that was given. Any help is appreciated. Thanks
....................................
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Lab0 { public static void main(String[] args) throws FileNotFoundException { String fileName = mode.txt";
File in = new File(fileName);
int frequency = countValues(in, 9);
System.out.println("\"9\" Count: " + frequency);
}
static int countValues(File inFile, int value) throws FileNotFoundException {
int freq = 0;
Scanner fileScanner = new Scanner(inFile);
while (fileScanner.hasNextInt()) {
int input = fileScanner.nextInt();
if (input == value) {
freq++; }
}
return freq;
}
}To my knowledge, this code tracks the occurrence of a single value. Thus I need to come up with an array that reads all digits in the file and tracks their occurrence, then returns the most frequent value. Hopefully this helps
