Scanner ask for and read file

Error:
exception FileNotFoundException is never thrown in body of corresponding try statement

import java.util.Scanner;
import java.io.*;

public class StringMenu {
public static void main(String[] args) {
try {
Scanner in = new Scanner(System.in);
System.out.print("Enter filename: ");
String filename = in.nextLine();

}
catch (FileNotFoundException e)
{
System.out.println ("File not found!");
System.exit (0);
}

}
}

Thread moved to Java forum.

You cannot create a catch block for an exception for a checked exception unless there is code in the corresponding try block that has the potential to throw that exception.
