Pull the numbers out of java jsoup

morde last edited by
I hope the last question is today. Using the library jSoup
That's the point. How do you extract the numbers from all the xml(s) from a specific current that no longer appear in the code? I honestly didn't find a lot of answers.
```
Document doc = Jsoup.connect("http://bcs-express.ru/kotirovki-i-grafiki/gazp").get();
Element title = doc.body();
System.out.println(title); 
```
How to get out of this whole page of what's in the current.
```
<div class="emet_index" data-placeholder="current">138,05</div>
```
The figures are particularly interesting. 138.05
Give me an example or a code. I didn't get the paperwork straight!

String html = "<div class='emet_index' data-placeholder='current'>138,05</div>";
Document doc = Jsoup.parse(html);
Element link = doc.select("div").first();
System.out.println(doc.body().text());

Each copy of the annex should add a unique reference code to the reference, and the billboard should start for requests with a reference code for the session, follow up on the session and record in the OBD that the target has been met.

Comparing JavaEE and designing under the Android is like comparing BELAZ and motorcycle driving. It's totally different things, and there's a lot of nuance and complexity. There's no need to choose technology on the principle of where the door is below and less knowledge is needed. If you need "speed and goodbye," you'll learn to slap on some CMS and a verbalpress, Joomla, etc., it'll be quick and simple.

You can do using the method eq() always 0, for every time it is sought in Html the class .box-hidden, always returns the first (0) element: $(".box-hidden").slice(0, 3).show(); $("#loadMore").on('click', function() { $(".box-hidden:hidden").eq(0).fadeIn("slow"); $(".box-hidden:hidden").eq(0).fadeIn(1500); $(".box-hidden:hidden").eq(0).fadeIn(2500); var boxes = $(".box-hidden:hidden").length; if(boxes == 0) { $("#loadMore").hide(); } });.wrap { margin: 100px; overflow: hidden; width: 600px; margin: auto; } .wrap .box { padding: 50px; background: #548614; float: left; margin: 10px; color: white; } .wrap .box-hidden { display: none; } .wrap-button { margin: auto; width: 120px; overflow: hidden; clear: both; } .wrap-button .btn-load { padding: 9px; display: block; color: #fff; background: #323232; }<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div class="wrap"> <div class="box box-hidden"> <p>Content 1</p> </div> <div class="box box-hidden"> <p>Content 2</p> </div> <div class="box box-hidden"> <p>Content 3</p> </div> <div class="box box-hidden"> <p>Content 4</p> </div> <div class="box box-hidden"> <p>Content 5</p> </div> <div class="box box-hidden"> <p>Content 6</p> </div> <div class="box box-hidden"> <p>Content 7</p> </div> <div class="box box-hidden"> <p>Content 8</p> </div> <div class="box box-hidden"> <p>Content 9</p> </div> <div class="box box-hidden"> <p>Content 1</p> </div> <div class="box box-hidden"> <p>Content 2</p> </div> <div class="box box-hidden"> <p>Content 3</p> </div> <div class="wrap-button"> <a href="#" id="loadMore" class="btn-load">Carregar mais</a> </div> </div>

Site, where do you want to evaporate information, it's likely that you can filter requests to the field of User Agent.To work on this site with Jsoup, it is necessary to establish a valid User Agent, for example:Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36 Code:public static void main(String[] args) throws IOException { Document doc = Jsoup.connect("https://elitedrop.ru/").userAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36").data("name", "jsoup").get(); System.out.println(doc); } successfully puts the HTML code on a given page.

What's happening to you is that, first you get the message out of whether it's cousin or not (which always returns that it is because the if is always fulfilled by your previous restrictions) and then check if it is.I'll fix the code.public static void main(String[] args) { Scanner sc = new Scanner (System.in); int num = 0; boolean esPrimo; while (num<5){ System.out.println("Ingrese un numero"); num= sc.nextInt(); esPrimo = primo(num) if(esPrimo){ System.out.println("El numero "+num+ " es primo"); }else{ System.out.println("El numero "+num+ " no es primo"); } sc.close(); } private static boolean primo(int num) { boolean prim = true; int divisor=2; while((prim) && (divisor!=num)){ if((num%divisor==0)){ prim=false; }else{ divisor++; } } return prim; }

Seeing that @matamans does not respond I put it to you: for bigger numbers than what fits in long You can use https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/math/BigInteger.html , specifically the method https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/math/BigInteger.html#multiply(java.math.BigInteger) .Note that multiply requires another BigInteger That in your case will be worth 2:BigInteger trigo = BigInteger.ONE; // BigInteger tiene valores ya definidos para 1, 2 y 10 for (int i = 0; i < 64; i++) { trigo = trigo.multiply(BigInteger.TWO); System.out.println("casilla "+(i+1)+":"+trigo+" Trigos"); }

Perhaps the function http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html#toPlainString() can serve that purpose.toPlainString: Returns the representation of string this BigDecimal without an exponent field. For values with a positive scale, the number of digits to the right of the decimal point is used to indicate scale.Here's an example: Double valorDouble = 7.89894691515E12; String valorStr = new BigDecimal(valorDouble).toPlainString(); System.out.println(valorStr); // 7898946915150 http://ideone.com/M5NLtn Update: I misunderstood the question, the above code does the opposite of what was asked, it converts a number with scientific format to string.To pass a number for scientific notation, for example https://pt.stackoverflow.com/questions/53704/como-passar-um-n%C3%BAmero-em-nota%C3%A7%C3%A3o-cient%C3%ADfica-em-java#comment110148_53704 , can be done so:DecimalFormat df = new DecimalFormat("0E0"); // Formato Double valorDouble = 10000000000.0; System.out.println(df.format(valorDouble)); // 1E10 http://ideone.com/YiOowC To pass a number with five decimal places for scientific notation, do so: DecimalFormat df = new DecimalFormat("0.0000E0"); Double valorDouble = 12345.0; System.out.println(df.format(valorDouble)); // 1.2345E4 http://ideone.com/rjn4QW If the format used is null, an exception NullPointerException will be released if it is invalid, IllegalArgumentException is released. No link below explains how to create and customize formats, although in English, it is quite understandable and contains examples. http://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html

Explaining in detail, step-by-step, how to develop the system is something out of scope. But basically you can use Spring Boot to make it easy for heavy work.The architecture is simple:The server needs to provide a channel via WebSockets so that the client (navigator) can receive updates.The page must have a JavaScript that subscribes to receive server updates (messages). https://spring.io/guides/gs/messaging-stomp-websocket/ you find a simple example. Over WebSockets, he uses a http://jmesnil.net/stomp-websocket/doc/ based on the STOMP protocol for text communication, more specifically, JSON.CustomerThe code in the client to connect, disconnect, send and receive messages is like this:function connect() { var socket = new SockJS('/hello'); stompClient = Stomp.over(socket); stompClient.connect({}, function(frame) { setConnected(true); console.log('Connected: ' + frame); stompClient.subscribe('/topic/greetings', function(greeting){ showGreeting(JSON.parse(greeting.body).content); }); }); } function disconnect() { if (stompClient != null) { stompClient.disconnect(); } setConnected(false); console.log("Disconnected"); } function sendName() { var name = document.getElementById('name').value; stompClient.send("/app/hello", {}, JSON.stringify({ 'name': name })); } The function showGreeting call in the first method would be responsible for displaying the message received.ServerYou can create a controller to receive and return messages:@Controller public class GreetingController { @MessageMapping("/hello") @SendTo("/topic/greetings") public Greeting greeting(HelloMessage message) throws Exception { Thread.sleep(3000); // simulated delay return new Greeting("Hello, " + message.getName() + "!"); } } Unfortunately, in this example of the tutorial, it only sends a message and ends.Already http://mpas.github.io/blog/2015/06/16/adding-websocket/stomp-support-to-a-spring-boot-application/ you find an example of how to publish messages on the channel is asynchronous (at any time):@Service public class ScheduleTask { @Autowired private SimpMessagingTemplate template; // this will send a message to an endpoint on which a client can subscribe @Scheduled(fixedRate = 5000) public void trigger() { // sends the message to /topic/message this.template.convertAndSend("/topic/message", "Date: " + new Date()); } } The configuration (as per the second tutorial) is like this:@Configuration @EnableWebSocketMessageBroker public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @Override public void registerStompEndpoints(StompEndpointRegistry registry) { // the endpoint for websocket connections registry.addEndpoint("/stomp").withSockJS(); } @Override public void configureMessageBroker(MessageBrokerRegistry config) { // use the /topic prefix for outgoing WebSocket communication config.enableSimpleBroker("/topic"); // use the /app prefix for others config.setApplicationDestinationPrefixes("/app"); } } DatabaseThe above examples do not consider databases. Unfortunately, receive database events or do polling (continuous check) in general are not possible or even recommended.The ideal is that your system contains some notification API where each new message manages a notification that goes to a queue. Eventually some asynchronous code can capture this message and publish in the correct channel, as in the example above where the scheduler publishes the date on the channel.Of course you can implement this synchronously, but usually this will generate very negative impacts on performance, so real applications don't do that.

Isa made this very simple model just to understand the dynamics. All in CSSBut I had to change your two <span> by <input> and one <label> using ::before Thus you can click the text or the image even and switch the image. The rest of the vc formatting does on the CSS of <label>See working on Snippethtml, body { width: 100%; height: 100%; margin: 10px; padding: 0; } label { cursor: pointer; } input[type="checkbox"]{ display: none; } input[type="checkbox"] + label::before { content: url(http://placeskull.com/40/40) } input[type="checkbox"]:checked + label::before { content: url(http://placecage.com/40/40) }<nav class="navbar navbar-fixed-left navbar-minimal animate open" role="navigation"> <div class="navbar-toggler animate"> <span class="menu-icon"></span> </div> <ul class="navbar-menu animate"> <li> <a href="#" class="animate"> <input type="checkbox" id="teste"> <label class="desc animate" for="teste">Tela Cheia</label> </li> </a> </ul> </nav>

Using part of your code I could do what you ask, which is not repeating a random number. To emulate your library random-number use Math.random() to generate random numbers and I put it to just look for random ones from 1 to 10 with:Math.floor((Math.random() * 10) + 1); The only thing I did was use Of index to determine whether the value already exists in that arrangement, if there is no assign to the array:var n1,n2,n3,n4,n5; var count = [n1,n2,n3,n4,n5]; for(var i in count) { var aleatorio = Math.floor((Math.random() * 10) + 1); console.log("Numero aleatorio "+aleatorio); if(count.indexOf(aleatorio) === -1){ count[i] = aleatorio; } } console.log(count);If in the array you get values "undefined" It is because I try to insert an existing value in the array, so leave it so that you will check that it does not repeat the values, but you can call a function where you call it if the value is repeated and look for a new one. I hope it serves you.

What happens to you is that you're comparing two kinds of objects String using the operator ==. This operator used on SIEMPRE objects compares references and as both references are different, although the content of the Strings is the same, as it is evaluated as false.To fix it uses instead of == method equals().persona1.getMail().equals(mailTxt.getText())// es tru si ambas cadenas contienen el mismo valor There are cases where the operator works == applied on objects of types StringBut you have to study the subject a little to see how it works. Look at this article: https://www.arquitecturajava.com/java-string-pool-un-concepto-importante/ As a general recommendation, avoid using the operator == about Strings, you'll be avoided by this kind of seemingly meaningless problems.

I'm afraid you don't know how it works. https://dev.mysql.com/doc/refman/8.0/en/counting-rows.html . Since the operator like will return true or false, and both countYour sentence is equivalent to this:SELECT count(1) AS 'Numero alumnos', count('X') AS 'Numero alumnas' FROM alumnos GROUP BY sexo; You realize the result is Right. because you are obtaining two rows, with an incorrect value in one of the columns and correct in the other, that is, both rows are incorrect, and this is because in reality the account she's doing it by grouping by sex (that's why you get two rows, because there are two sexes), but it's not what you want.Stop. count records based on a condition like the one you pose, actually what you want to do is, for each row, add 1 in the first column if it is man, and add 1 in the second column if it is woman. To return 1 or 0 as the case is, we can use a caseor function if()Using a case, the consultation would be something like:select sum(case when sexo = 'H' then 1 else 0 end) as NumeroAlumnos , sum(case when sexo = 'M' then 1 else 0 end) as NumeroAlumnas from alumnos As you can see, I have not included any grouping, since what you are looking for is that the query returns a single row with both columns.If, on the contrary, two rows are Good. for you, you can simplify even more by doing:select sexo, sount(1) from alumnos group by sexo
