从LinkedList创建队列

Question

I have a problem with creating a Queue object.I dont know what is wrong.

My code:

import java.util.*;
public class Demo {
    public static void main(String[] args) {

        Queue<Integer> q = new LinkedList<Integer>();


    }
}

Compiler error:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The type LinkedList is not generic; it cannot be parameterized with arguments

Answer 1

might be a name conflict ( see if you have a class named LinkedList somewhere in your default package )

Try this -

 Queue<Integer> q = new java.util.LinkedList<Integer>();
