    Default My code doesn't show the right output

    So I have a file with the following values : 3,455;1,67;83,98;0,1;23,178;2.45;3.5;16,88. The code shows the values to the user and it must decide which number is largest and smallest. This is what I've written but I get a different output that what it's supposed to show.

     import java.io.File;
    import java.util.Scanner;
    import java.io.IOException;
    public class NumbersNew {
    	public static void main(String[] args) throws IOException {
    		//Create a scanner object which will read the data from the file
    		Scanner sc = new Scanner(new File("/Users/sergeapplemac/Documents/workspace/NumbersNew/src/Numbers2.txt"));
    		while (sc.hasNextLine()) {
    			//Determine which number was the greatest and which one was the least
            double largest = Double.MIN_VALUE;
            double smallest = Double.MAX_VALUE;
    		while(sc.hasNextDouble()) {
                double val = sc.nextDouble();
                if (val < smallest) {
                	smallest = val;
                if(val > largest) {
                    largest = val;
    		//Print these numbers
            System.out.println("The biggest number in the file is: " + largest);
            System.out.println("The smallest number in the file is: " +smallest);

    This is the output that I get and I don't understand why:

    The biggest number in the file is: 4.9E-324
    The smallest number in the file is: 1.7976931348623157E308.

    Can anyone make a suggestion or point me in the right direction? Thank you!
