Document

Creates a JScrollPane that displays the contents of the specified component, where both horizontal and vertical scrollbars appear whenever the component's contents are larger than the view.

Usage

From source file:Main.java

public static void main(String[] args) {
    JFrame f = new JFrame();
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Vector<Vector<String>> rowData = new Vector<Vector<String>>();
    Vector<String> columnName = new Vector<String>(Arrays.asList("Column 1"));
    for (int i = 0; i < 2000; i++) {
        rowData.add(new Vector<String>(Arrays.asList(Integer.toString(i))));
    }// www  .  j  a v  a2 s  .  c o  m
    JTable table = new JTable(rowData, columnName);
    JScrollPane scrollPane = new JScrollPane(table);
    JScrollBar vertical = scrollPane.getVerticalScrollBar();
    vertical.setPreferredSize(new Dimension(0, 0));
    f.add(scrollPane);
    f.pack();
    f.setVisible(true);
    JViewport view = scrollPane.getViewport();
    Component[] components = view.getComponents();
    for (int i1 = 0; i1 < components.length; i1++) {
        if (components[i1] instanceof JTable) {
            System.out.println("got");
        }
    }
