I'm new in Java Swing and try to use of Scroll pane on my Java code, but it's not working. The Scroll Pane is add on the frame in vertical direction but not worked.

You should create your own panel that extends JPanel containing all checkboxes and in this panel override getPreferredSize() method like:

@Override

public Dimension getPreferredSize()

{

    return new Dimension( 300,300 );

}

and use it in your code:

...



// creating the scroll pane that will scroll the panel.

JScrollPane jscrlPane = new JScrollPane( new MyPanelWithCheckboxes() );

jscrlPane.setBounds( 0, 0, 300, 300 );

...

Don't use setPreferredSize() when you really mean to override getPreferredSize().
