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 draw lines using the mouse than with 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, if you wanted to write PC Paint 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.
