1.6 Basic Program Design

In the preceding sections of this monograph, we studied a Java subset suitable for explicating the basic principles of Java program design. As you recall from your Scheme background, the process of program design can be broken down into six steps:

• Data Analysis and Design
• Contract and Header
• Examples
• Template
• Body
• Test

which we collectively call the design recipe. Let us examine each of these six steps in the context of writing object-oriented programs in Java.
