How to Rotate Text 90 Degree?

Question

I tried to rotate text so that it reads from bottom to
top of the screen (vertically). How to do it?
I tried w/ Graphics2D and AffineTransform class but fail.
Here is my code:
AffineTransform af = new AffineTransform(0.0, 1.0, 1.0,
0.0, 0.0, 0.0);
Graphics2D newg = (Graphics2D) g;
g.setTransform(af);
g.drawString("Rotated Text", 70.0f, 70.0f);
Anybody do text rotation please post reply.
Thanks!

Turns out the bug still persists, and I post new Q on
this forum. Please check it out.
But here is the my entire code, if you would like to see
and try:
import javax.swing.DefaultCellEditor;
import javax.swing.JScrollPane;
import javax.swing.SwingConstants;
import javax.swing.JPanel;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
import java.text.NumberFormat;
import java.text.DecimalFormat;
import java.awt.Graphics2D;
import java.awt.geom.AffineTransform;

AffineTransform af2 =
AffineTransform.getRotateInstance(Math.toRadians(270), xp, yp);
g2.setTransform(af2);
