Thread: 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?
