	private class ButtonHandler implements ActionListener
	{
		public void actionPerformed( ActionEvent event )
		{
			System.out.println( "Pressed" );
			if( getSelectedIndex() == 0 )
			{
				department.setName( "CSE" );
				System.out.printf( "%s", department.getName() );
			}
			if( getSelectedIndex() == 1 )
			{
				department.setName( "EE" );
			}
			if( getSelectedIndex() == 2 )
			{
				department.setName( "Physics" );
			}
			if( getSelectedIndex() == 3 )
			{
				department.setName( "Biology" );
			} 
			
		}
	}
	
}

When I click the JButton "select" I dont think it is registering it as an event. The system.out.println() is not showing up.

I think you need either selectJButton.getSelectedIndex() or event.getSelectedIndex()

[Fubarable]

Does your code even compile? I'm getting a lot of compile errors as you seem to be calling methods and referencing objects that don't exist.

i think that getSelectedIndex() is referred to the JList names,so it should be

..................
names.getSelectedIndex()..........

But what is that object with the name department which has also the getName() mehtod?
