Example of changing the colour of the current graphics context

Extending the previous example, we can create an applet to draw blue text in its window to produce the following output:

by simply adding a statement to change the colour of the graphics context before drawing the string.

So we must send a setColor() message to the Graphics object before sending the drawString() message:

import java.applet.Applet;

import java.awt.*;

public class DrawString2 extends Applet
{

public void paint( Graphics g )
{
    g.setColor( Color.blue );
    g.drawString( "text drawn with Graphics method 'drawString()'",
       20, 20 );
}

} // class
