    Default Beginner, Reading from file error

    Hello, I have just done a program in Java that reads from a file, stores the values and the prints them, though I have a small problem.

    public class Read {
     
    	public static void main(String[] args) throws Exception {
     
    		File testFile = new File("me.txt");
    		Scanner scan = new Scanner(testFile);
     
    		String name;
    		int phone;
     
    		name = scan.nextLine();
    		phone = scan.nextInt();
     
    		System.out.println("Name: " + name);
    		System.out.println("Phone: " + phone);
     
    		scan.close();
          }
    }

    I get the error:

    Exception in thread "main" java.util.InputMismatchException: For input string: "07983857686"
    	at java.util.Scanner.nextInt(Unknown Source)
    	at java.util.Scanner.nextInt(Unknown Source)
    	at week3.ReadMe.main(ReadMe.java:28)

    If I change the phone number from int to String it works, though I wan't to know why? The phone numbers is made up of only numbers, so It must be due to the 0 in front?

    Did you try it without the 0? What happened?

    Try to use FileReader instead of File, and come-back with an update. I know for sure that with FileReader should work because I used it recently.
