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 may recall from your prior exposure to program design in Scheme, the process of program design can be broken down into six steps:

• Problem Analysis and Data Design
• Contract, Header, and Purpose
• 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.
