JTable - row focus color

Question

I wrote a program which will change the color of each row.
odd row background color will be white
even row background color will be gray.
My doubt is?
if i move the mouse on the any row, that row should have a different background color (dark of row background)

I tried with DefaultTableCellRenderer, but it is not
workingIs this what you want?
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.TableCellRenderer;
public class RowColor extends JFrame {
    public RowColor() {
        Object[][] data =
            {"Row 1", "Row 1"},
            {"Row 2", "Row 2"},
            {"Row 3", "Row 3"},
            {"Row 4", "Row 4"}
        Object[] columnNames = {"Column 1","Column 2"};
        JTable table = new JTable(data, columnNames) {
            public TableCellRenderer getCellRenderer(int row, int column){
                DefaultTableCellRenderer c = (DefaultTableCellRenderer)super.getCellRenderer(row, column);
                if (row % 2 == 0)
                    c.setBackground(Color.GREEN);
                else
                    c.setBackground(Color.YELLOW);
                return c;
        JScrollPane scrollPane = new JScrollPane( table );
        getContentPane().add( scrollPane );
    public static void main(String[] args) {
        RowColor frame = new RowColor();
        frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
}
