Katas

Code Katas are short programming exercises meant to hone your skills through repetition. They’re also handy for learning new languages, practicing your keyboard skills, and more. Here’s a collection of some of the neater ones I’ve ran across:

• Guilded Rose
• Bowling Game
• String calculator (and part 2)
• Big collection of random katas
• String stack - have it throw an exception for popping an empty stack, pop a single item, and pop two items correctly
• Dollar amount to wording - convert a given dollar amount (say $1,132.53) to wording like you’d use on your checks (“one thousand, one hundred thirty two and 53/100”)
• App Katas
• Collection of various exercises & katas
• Project Euler (anything from there)
• Roman Numerals
• A listing of different katas
• Team Dojo - a kata for a small group that Jason Gorman ran at Software Craftsmanship 2012. Great exercise!
• Ordered Jobs
• Composition Kata
• The Xmas Train Kata
• Architecture katas
• Kata Log
