QUESTION 9:
How could you draw ten red circles across an applet's drawing area?
No. Using PC Paint, or some other drawing tool would be a better way to make such a picture. It is much easier to create a picture with a painting program than by progamming.
The reason for these lessons on Java graphics commands was to show what they do. Usually they would not be used in drawing a picture as in this example. They would usually be used as part of a program that is interacting with the user or with a file of data to produce a picture. For example, to write a painting program in Java, you would certainly use all of these commands.
There situations where a picture consists of a vast number of elements that can be computed by a program, but are too numerous for a human to specify each one with a mouse or other means. The next example is a simplified example of this.
