You need to import java.util.Queue and java.util.LinkedList, the same way you did with java.io.File. See this link for more information .

 import java.util.Queue;
 import java.util.LinkedList;

 import java.io.File;
 import java.io.FileNotFoundException;

 import java.util.Scanner; 

 public class ask1 {

    public static void main(String[] args) {
       // your code...
    }
 }
