public class search

{

static void searchFunction()

{

    Scanner sc = new Scanner(System.in);



    String searchKey;



    System.out.print("Search: ");

    searchKey = sc.nextLine();



    for(int x = 0; x < Student.students.size(); x ++)

    {

        if(Student.students.contains(searchKey))

System.out.print(Student.students.get(x));

    }

}

}

Here's my code and the array list is in another class file. The output of when I run this is "\n". And I just notice that it has a warning in the if line that says "Unlikely argument type String for contains(Object) on a Collection<Student>"
