Java - Scrollable Menu

Good morning Junior

It is possible using a JScrollPane, add one or more Component (s) to it and then add it to the frame you are using, be it a JFrame or another.

Ex:

public class Exemplo {
   public static void main(String[] args) {
       JFrame jFrame = new JFrame();
       JPanel jPanel = new JPanel(); //component
       JScrollPane pane = new JScrollPane(jPanel); 
       jFrame.setContentPane(pane);
   }
}
