GUI building in JAVA ....adding components on click

Question

swing library has been added (working in Netbeans)
JButton btn=new JButton(b);
JTextFeild txt=new JTextFeild("textfeild");
txt.setbounds(10,50,100,20);
btn.addActionListener(new ActionListener(ActionPerformed{btn.add(txt)}));
I can't share whole code because it's too lengthy and also I don't know how to import codes
thanks

Answer 1

I think most people have moved away from swing, take a look at JavaFX
