In an application, a programmer usually provides a page for donations. Usually they use USD, Bitcoin, Etherium or other currencies. Here I will try to make a donation page for java application using USD, STEEM and SBD. for STEEM and SBD, I use steemconnect. As for USD, use Paypal. I hope this becomes a reference for those of you who are java language programmers.

Directly, Lets follow steps bellow to create this application :

Create a form

• Open your Netbeans IDE and create new project
  
  

• Delete donate.java class and create new JFrameForm
  
  

Design the Form

• Add jLabel for the title
  

• Add TabbedPane to create donation tabs
  

• Add 3 panel on TabbedPane, For USD, STEEM and SBD donation
  
  

• Create form for tab1, tab2, and tab3. Tab1 for USD, Tab2 for STEEM and tab3 for SBD. The form contain 2 textfield and 1 button, like image bellow :
  

• Rename the textfield and button with different variable name. You can see my variable
  

Edit Source Code

• open donate usd tab on design and double click on send button until appear like image bellow then add some method
  

• Right click on hint simbol on left side on code and click on add donateUsd method

• Go to donateUSD() method and add the code bellow :

        String usdR=usdReceiver.getText();
        String usd=usdAmount.getText();
        final JFrame frame=new JFrame();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setSize(1280,720);
        final JFXPanel fxpanel=new JFXPanel();
        frame.add(fxpanel);
        Platform.runLater(new Runnable(){
            @Override
            public void run() {
                WebEngine engine;
                WebView wv =new WebView();
                engine=wv.getEngine();
                fxpanel.setScene(new Scene(wv));
                engine.load("https://www.paypal.me/"+usdR+"/"+usd+"USD");         
            }
        });
        frame.setVisible(true);

Code	Explanation
usdReceiver.getText()	get text from receiver textfield
usdAmount.getText()	get text from amount textfield
frame	the variable name for new JFrame. You need to import package javax.swing.JFrame for using JFrame
setDefaultCloseOperation	method to set the the exit button on right-top corner
setSize()	method to set the width and height of the new frame
final JFXPanel fxpanel=new JFXPanel()	Initialize new JFX panel
frame.add(fxpanel)	add JfxPanel to JFrame
Platform.runLater	method to run some task on JFXpanel
@Override	to implement all abstract method
WebEngine engine	Inizialize web engine
WebView wv =new WebView()	Inizialize new web view
engine=wv.getEngine()	get view from web engine
fxpanel.setScene(new Scene(wv))	set scene on JFXpanel
engine.load	load some url
https://www.paypal.me/"+usdR+"/"+usd+"USD	Paypal.me link to get USD. Here we costume it with receiver and amount in input from form.

• Now go to donate steem tab and double click on send button and add donateSteem() method then add this code in that method, like this :

private void donateSteem() {
        String steemR=steemReceiver.getText();
        String steem=steemAmount.getText();
        final JFrame frame=new JFrame();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setSize(1280,720);
        final JFXPanel fxpanel=new JFXPanel();
        frame.add(fxpanel);
        Platform.runLater(new Runnable(){
            @Override
            public void run() {
                WebEngine engine;
                WebView wv =new WebView();
                engine=wv.getEngine();
                fxpanel.setScene(new Scene(wv));
                engine.load("https://steemconnect.com/sign/transfer?from=you&to="+steemR+"&amount="+steem+"%20STEEM&memo=Donations");         
            }
        });
        frame.setVisible(true);
    }

Code	Explanation
steemReceiver.getText()	get text from receiver textfield for STEEM
steemAmount.getText()	get text from amount textfield for STEEM
https://steemconnect.com/sign/transfer?from=you&to="+steemR+"&amount="+steem+"%20STEEM&memo=Donations	steemconnect link for transferring STEEM to another account. here I costume the link for the to and amount value are from the user input and I set Donations for memo value.

• Last one go to Donate SBD tab then do as you do on Donate SBD tab. and add the code bellow in donateSBD() method :

        String sbdR=sbdReceiver.getText();
        String sbd=sbdAmount.getText();
        final JFrame frame=new JFrame();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setSize(1280,720);
        final JFXPanel fxpanel=new JFXPanel();
        frame.add(fxpanel);
        Platform.runLater(new Runnable(){
            @Override
            public void run() {
                WebEngine engine;
                WebView wv =new WebView();
                engine=wv.getEngine();
                fxpanel.setScene(new Scene(wv));
                engine.load("https://steemconnect.com/sign/transfer?from=you&to="+sbdR+"&amount="+sbd+"%20SBD&memo=Donations");         
            }
        });
        frame.setVisible(true);

Code	Explanation
sbdReceiver.getText()	get text from receiver textfield for SBD
sbdAmount.getText()	get text from amount textfield for SBD
https://steemconnect.com/sign/transfer?from=you&to="+steemR+"&amount="+steem+"%20SBD&memo=Donations	steemconnect link for transferring SBD to another account. here I costume the link for the to and amount value are from the user input and I set Donations for memo value.
