Answer 1

import java.util.LinkedList;

public class MyClass {
    public static void main(String args[]) {
        LinkedList<String> ll = new LinkedList<>();

        ll.add("Java");
        ll.add("C++");

        ll.addFirst("C");

        ll.addLast("Python");
        
        System.out.println("LinkedList: " + ll);

        System.out.println("First Element: " + ll.getFirst());

        System.out.println("Last Element: " + ll.getLast());
        
        ll.remove("Python");
        
        System.out.println("LinkedList: " + ll);
    }
}




/*
