How to add multiple data in JTextField?

I want to add data from JTextField but if I pressed the process again, the data that I write is missing. Is there any solution for this code?

try{
    txttujuan.removeAll();
    int xxx=0;
    String XNilai,Nilai;
    for (xxx=0;xxx <jtable.getRowCount();xxx++){

        if (jtable.getValueAt(xxx,4).equals("1")){
            Nilai ="0"+ (String) jtable.getValueAt(xxx,2);   
            XNilai+=Nilai+",";       
        } else continue;     
        System.out.print(XNilai.substring(0,XNilai.lastIndexOf(",")));
        jtextfield.setText();
        jtextfield.setText(XNilai.substring(0,XNilai.lastIndexOf(",")));
        XNilai="";
    }

} catch (Exception e){
    System.out.print(e);
}

my data i've already wrote is missing

That is what the setText() method does. It replaces the existing text with the new text.

Instead of using a JTextField you can try using a JTextArea, then you can use the following to add text to the end:

textArea.append( "some text" );

If you really want to use a JTextField then you can use:

Document doc = textField.getDocument();
doc.insertString("some text", doc.getLength(), null);

to append text to the text field.
