In wireless LANs ( wireless local area networks), the hidden terminal problem is a transmission problem that arises when two or more stations who are out of range of each other transmit simultaneously to a common recipient. This is prevalent in decentralised systems where there aren’t any entity for controlling transmissions. This occurs when a station is visible from a wireless access point (AP), but is hidden from other stations that communicate with the AP.Problem IllustrationSuppose that there are three stations labelled STA, STB, and STC, where STA and STC are transmitting while STB is receiving. The stations are in ... Read More
Use the getSiblingCount() method to get the number of siblings of a node in JTree. For example, let’s say we have a node, which isn’t a root node. For that, we will find the sibling count −node1.getSiblingCount()The following is an example to get the number of siblings of a node −package my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.tree.DefaultMutableTreeNode; public class SwingDemo { public static void main(String[] args) throws Exception { JFrame frame = new JFrame("Demo"); DefaultMutableTreeNode node = new DefaultMutableTreeNode("Project"); DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("QA"); DefaultMutableTreeNode node2 ...

To compare multiple properties, use the $where operator. Let us first create a collection with documents −> dbcomparingMultiplePropertiesDemoinsertOne({"Values":[10, 70, 60]}); { "acknowledged" : true, "insertedId" : ObjectId("5cf228fcb64a577be5a2bc0a") }Following is the query to display all documents from a collection with the help of find() method −> dbcomparingMultiplePropertiesDemofind()pretty();This will produce the following document −{ "_id" : ObjectId("5cf228fcb64a577be5a2bc0a"), "Values" : [ 10, 70, 60 ] }Case 1: If condition becomes true then you will get an array otherwise nothing will get displayed Following is the query to compare multiple ...

The rect() method of the HTML canvas is used to create a rectangle. The element allows you to draw graphics on a web page using JavaScript. Every canvas has two elements that describes the height and width of the canvas i.e. height and width respectively.Following is the syntax −context.fillRect(p, q, width, height);Above, p: The x-coordinate of the upper-left corner of the rectangleq: The y-coordinate of the upper-left corner of the rectanglewidth: Width of the rectangleheight: Height of the rectangleLet us now see an example to implement the rect() method of canvas −Example Live Demo Your browser does ...

You can convert a character to upper case using the toUpperCase() method of the character class.ExampleFollowing program converts alternate characters of a string to Upper Case. Live Demoimport java.util.Scanner; public class UpperCase { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter a string :"); String str = sc.nextLine(); str = str.toLowerCase(); char[] ch = str.toCharArray(); for(int i=0; i
The HTML DOM removeNamedItem() method removes the node specified in its parameter from an attribute node using its name in an HTML document.SyntaxFollowing is the syntax −node.removeNamedItem(node);ExampleLet us see an example of removeNamedItem() method − Live Demo html{ height:100%; } body{ text-align:center; color:#fff; background: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%) center/cover no-repeat; height:100%; } .btn{ background:#0197F6; border:none; height:2rem; border-radius:2px; width:60%; margin:2rem ...

Sometimes we need to know that, what is the current C++ standard. To get this kind of information, we can use the macro called __cplusplus. For different standards, the value of this will be like below.Standard__cplusplus outputC++ pre C++981C++98199711LC++98 + TR1This cannot be checked, this will be marked as C++98C++11201103LC++14201402LC++17201703LExample#include int main() { if (__cplusplus == 201703L) std::cout
Auto layout is constraint based layout system used for development of User Interfaces for iOS Devices. This layout based constraint system also known as Auto Layout is basically an adaptive UI which adapts to screens of different sizes and orientations.Auto layout is completely dependent on constraints where developer defines a relation between neighbouring or parent element to seize it position.Why Auto Layout?While designing an iOS application you need to make sure, the UI which you’re developing should be equally compatible with all screen sizes and orientation. Auto layout comes handy when you wish to do so.Consider below images. A centrally ... Read More
