How to Display JTable with Horizontal and Vertical Scrollbars

import java.util.Vector;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.ScrollPaneConstants;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumn;

class JTableScrollPane extends JFrame {
Vector columns = new Vector();
static Vector

public JTableScrollPane() {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
JTable table = new JTable();
String[] columnNames = { “Column1″, “Column2″ };
addColumns(columnNames);
DefaultTableModel defaulttablemodel = new DefaultTableModel();

for (int i = 0; i < 60; i++) {
Vector vect = new Vector();
vect.addElement(“test”);
rows.addElement(vect);

}

defaulttablemodel.setDataVector(rows, columns);
table.setModel(defaulttablemodel);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
int v = ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS;
int h = ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS;
int vColIndex = 1;
TableColumn col = table.getColumnModel().getColumn(vColIndex);
int width = 400;
col.setPreferredWidth(width);

JScrollPane scroll = new JScrollPane(table, v, h);
scroll.setViewportView(table);

scroll.setAutoscrolls(true);
panel.add(scroll);
frame.add(panel);
frame.setSize(500, 500);
frame.setVisible(true);

}

private void addColumns(String[] colName)// Table Columns
{
for (int i = 0; i < colName.length; i++)
columns.addElement(colName[i]);
}

public static void main(String[] args) {
new JTableScrollPane();
}
}
