public class Frame extends JFrame {
	public Frame() {
		setTitle("Control wheel speed of JScrollPane");
		setSize(500, 500);
		getContentPane().setLayout(null);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		JScrollPane jsp = new JScrollPane();
		jsp.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
		jsp.getVerticalScrollBar().setUnitIncrement(16);	//스크롤 속도
		jsp.setBorder(null);
		jsp.setBounds(10, 10, 470, 470);
		add(jsp);

		JPanel panel = new JPanel();
		panel.setPreferredSize(new Dimension(450, 1000));
		panel.setLayout(null);
		jsp.setViewportView(panel);

		JTextArea textbox = new JTextArea();
		textbox.setBounds(0, 0, 450, 1000);
		panel.add(textbox);
		
		setVisible(true);
