Some Code examples

• wombat.ss, a definition by parts
• employee.ss, another definition by parts
• animal.ss, a definition by choices from structs defined by parts
• shapes-lab.ss, a series of exercises combining definition by choices with definition by parts
• employees.ss, a list of structs defined by parts
• animals.ss, a list of a data type defined by choices
• ftree.ss, a bottom-up family tree data type
• Java Examples.zip, a folder containing a Shape project and several successive versions of an IntList project to see how to make the transition from recursion to loops:
  1. addUp by structural recursion;
  2. addUp by accumulative recursion;
  3. addUp moved outside the IntList class into a recursive static method;
  4. addUp written with a foreach loop using IterableAdapters; and
  5. addUpwhile loop using standard Java Iterators
