A good answer might be:

It sets the background of the screen area to be painted to pink. (However, some browsers will not change the color, depending on how they have been set up.)

Graphics Objects

The background color of the applet is the color of the drawing area. It can be set to a pre-defined color or to a custom color. This will be discussed further in a few pages.

In order to connect your applet to the particular area of the screen to be painted, the Web browser must pass your paint() method a reference to a Graphics object. This object represents the part of the screen filled the applet. A Graphics object has many methods for doing graphical things. It is somewhat like a "paint" program that has methods to draw lines, draw circles, write text, and so on. The statement:

gr.drawString("Loveliest of trees, the cherry now", 25, 30);

calls the method drawString() of the Graphics object. It prints the string at the location given by the last two parameters, 25 pixels from the left edge of the applet's area and 30 pixels from the top edge.

drawString( String str, int  x, int  y)

The x and y parameters tell where to place the string within the applet's area. This is like graph paper, except the (0,0) location is the upper left corner (of the applet's area, not of the full screen.) Increasing y values move down the area. The location specified by (x, y) is where to place the lower left part of the first character of the String.

Distance is measured in pixels. A pixel is one of the graph paper squares that the video screen has been (conceptually) divided into. If you have set your monitor to a resolution of 800 by 600, then the screen is divided into 800 horizontal squares and 600 vertical squares. It is the responsibility of the graphics card and its driver to implement this idea of graph paper on the actual electronics of you computer system.

A pixel is not one of the little, glowing dots of phosphor on the monitor screen. Depending on the resolution you are using, an image pixel may correspond to several of these dots or a fraction of one dot.


Here is part of the applet:

gr.drawString("Loveliest of trees, the cherry now", 25, 30);
gr.drawString("Is hung with bloom along the bough", ________, _________ );

Suggest a location for the second line (assume that characters are 10 pixels high.)
