Sprint 4

Roadmap:

Team assignments: Section A; Section B
Start: 2nd half of class, Thu 10/19
End: Quiz in 1st half of class, Thu 11/2
Requirements Due: beginning of class, Thu 11/2

Rationale:

In the previous sprint, we learned how to allow the user to enter a variable number of inputs and report on various characteristics of those inputs. But what if we would like to analyze and reanalyze those inputs? We could, for example, create 100 variables to store each input entered by a user, but then we would be limited to 100 inputs and would also have to keep track of which variables are being used and which aren’t when the user has fewer than 100 inputs. This would quickly become quite a coding mess.

When we need to conduct a variety of analyses on a sequence of values, a list provides a fairly straightforward way to manage the values. In this sprint, we learn about a particular type of list in Java (the ArrayList) and learn about key methods and processes for manipulating and analyzing lists.

Responsibilities (What you need to know):

In previous sprints I provided a generic list of responsibilities. In this sprint I am strongly recommending that all students engage in all of the following materials.

Read Working with Lists in Java
Engage with online materials

The textbook also has a chapter section on ArrayList (Ch. 7.7), but it assumes knowledge of a Java concept called arrays. We’ll address arrays in Sprint 5. If you’d like to read Ch. 7.7 please do, but you may want to wait until Sprint 5.

Requirements (What you need to do):

Individual Requirements:

Understand the concepts on the Responsibilities list.

Team Requirements:

Complete the code in this project. All instructions are contained in the project comments.
