Special methods of java---LinkedList

Special methods of LinkedList

The unique methods are:

test:

LinkedList list = new LinkedList();
        list.add("你好呀");
        list.addFirst("Hello");
        list.add(45);
        list.addLast("123");
        list.addLast("world");
        list.addLast("nice");
        for (int i = 0; i < list.size(); i++) {
    
    
            System.out.println(list.get(i));
        }
        System.out.println("------------");
        System.out.println(list.getFirst());
        System.out.println(list.getLast());
        System.out.println(list.remove(1));
        System.out.println(list.removeFirst());
        System.out.println(list.removeLast());
        System.out.println("-----------");
        for (int i = 0; i < list.size(); i++) {
    
    
            System.out.println(list.get(i));
        }
