The completed applet is given below.
In this example applet, the x and y values for the start of the String are written as arithmetic expressions. The expression for x starts the string at the point half the string size to the left of half the drawing area's width. The expression for y starts the string at the point half the character size down from half the drawing area's height. Because going down the page means increasing Y, 10/2 is added to the center Y value. (There is a better way to do this, but it uses a few more methods.)
import java.applet.Applet;
import java.awt.*;
public class AnotherHello extends Applet
{
public void paint ( Graphics gr )
{
setBackground( Color.lightGray );
gr.drawString("Hello", (300/2 - 40/2), (150/2 + 10/2) );
}
}
Here is what the applet looks like:
