2 - 5 p.m. Coordinated Universal Time

This event has ended.

What you’ll learn and how you can apply it

  • Keen insight into the motivation for clean code
  • Practical advice on the proper size and structure of functions
  • Several practical heuristics for naming classes, functions, and variables
  • Guidance on when and where to write comments, and when not to
  • Simple and actionable rules for code formatting

This live event is for you because…

  • You are an application developer, programmer, software engineer, or software architect who works with code.
  • You take pride in your organization’s development efforts, understand the basis of software development, and appreciates how the code base can impact the entire development organization.
  • You want to learn how to build clean code, and help others in your organization do so, too.


  • There are no prerequisites for this Clean Code training session, but it would be optimal if participants have practical software development experience and familiarity with the terminology and practices around code construction and maintenance.



The timeframes are only estimates and may vary according to how the class is progressing.

Introduction (10 min)

Section 1 Names (30 min)

  • Names are everywhere in software. We name our variables, our functions, our arguments, classes, and packages. We name our source files and the directories that contain them. We name our jar files and war files and ear files. We name and name and name. Because we do so much of it, we’d better do it well. What follows are some simple rules for creating good names.

Break (5-10 min)

Section 2: Functions (45 min)

  • In the early days of programming we composed our systems of routines and subroutines. Then, in the era of Fortran and PL/1 we composed our systems of programs, subprograms, and functions. Nowadays only the function survives from those early days. Functions are the first line of organization in any program. Writing them well is the topic of this chapter.

Section 3: Comments (30 min)

  • Nothing can be quite so helpful as a well-placed comment. Nothing can clutter up a module more than frivolous dogmatic comments. Nothing can be quite so damaging as an old crufty comment that propagates lies and misinformation.

Break (5-10 min)

Section 4: Formatting (30 min)

  • You should take care that your code is nicely formatted. You should choose a set of simple rules that govern the format of your code, and then you should consistently apply those rules. If you are working on a team, then the team should agree to a single set of formatting rules and all members should comply. It helps to have an automated tool that can apply those formatting rules for you.

Conclusion (20 min)

  • Q&A
