Methods inherited from interface java.util.JComboBox (javax. A that additionally supports operations that wait for the queue to become non-empty. Returns the text value of all of the elements in the collection. Collection parallelStream, stream, toArray Creates a new NodeList containing the same elements as the original (but cloned in the case of Nodes. Increment the value of count by 1 for each node encountered in the list. Traverse through the list till current point to null. Declare and initialize a variable count to 0. They both have a length property to display the number of items in a collection, each of which can be accessed by. Define a node current which will initially point to the head of the list. Both of their items refer to HTML elements: HTMLCollection is a collection of HTML elements, while a NodeList is a collection of element nodes. Methods inherited from interface java.util. JavaScript NodeList is nearly the same as HTMLCollection.All browsers return a NodeList object for the property childNodes.
Some (older) browsers return a NodeList object instead of an HTMLCollection for methods like getElementsB圜lassName(). A NodeList object is almost the same as an HTMLCollection object. My problem is that I keep getting a null pointer exception after the staff1 tag, i.e. A NodeList object is a list (collection) of nodes extracted from a document.

We replace the head node with a new node. See also the Document Object Model (DOM) Level 3 Core Specification. The items in the NodeList are accessible via an integral index, starting from 0. And we make the newly added node as null. The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. Method Summary All Methods Instance Methods Concrete Methods Modifier and Type For inserting the node at the end we simply copy the address of the node to be added to the last node.Constructor Summary Constructors Constructor.Fields inherited from class java.util.
