java app for crypto market

 Hello dear steemit friends,
today i am  going to show you how to create small java application for coin market.  first you need to small things.
1.small java knowledge2.java development kit ( JDK ) you can download3.IDE ( i am using netbeans )4.small brain5.1 laptop 6.2 hand7.jsoup library

 ok guys, now  we are ready for do that. 
 install netbeans ide and after 
1. file >> New project >> Java >> Java application >> project name and path >> finish


fisrt you need to design this user interface using netbeans ide or another ide.
THIS IS VERY IMPORTENT :  add jsoup libry to you project. google " how to add libry to netbeans project"

and we are going to code our application.  no no it is not complicated. too easy . 
 double click "start market button" or right click  Event >> action >> action performed then code like this.

    javax.swing.Timer t;
        t = new javax.swing.Timer(1000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {


                Document doc;
                try {


                    String y=a.getText();
                   
                    // need http protocol
                    doc = Jsoup.connect("https://coinmarketcap.com/currencies/digibyte/").get();


                    Elements divTag = doc.getElementsByClass("text-gray");


                    System.out.println(divTag.text());


                    String x = divTag.text().toString();
                    String fi = "";
                    for (int i = 0; i < 11; i++) {


                        char c = x.charAt(i);
                        fi = fi + c;
                    }
                    System.out.println(fi);


                    ta.setText(fi);
                    
                  
                    
                    if (ta.getText().equals(a.getText())) {
                        System.out.println("yes");
                        Toolkit.getDefaultToolkit().beep();
                        
                    }


                } catch (java.net.UnknownHostException rt) {


                   
                    JOptionPane.showMessageDialog(createRootPane(),"not a internet connection");
                     System.exit(0);
                } catch (IOException d) {
                }


            }
        });
        t.start();

      thats it. now you can run your java application. and click start market button its will gave values.

   " doc = Jsoup.connect("https://coinmarketcap.com/currencies/dash/").get();"      i think you are enjoying this article.  i hope to another  tutorial for   crypto application.    you can develop this application. this is too small.    hope you learn something.
