Another task I originally solved with a 1-liner in C# and which I had to reimplement in Java, because C# editor broke for me… Anyways, idea is simple, solution is verbose, job’s done. ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 «CodeHunt» An […]

I figured this one out quickly. I implemented it quickly, in C#. Now for the recording suddenly the C#-editor broke for me. Can’t fix it. Solved the task in Java instead. Quite verbose… does it give you the full skill rating? ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► Let’s Develop! http://letsdeveloper.com […]

This one took me quite some time to figure out. Main reason were the test cases that were not generated for the inputs I provided, which made it hard for be to find the pattern… the actual implementation was quite easy then. My algorithms teacher would kill me for the […]

Branching over data should be close to where the data. Because if I ever change the data’s semantics in the future, I see the branching that depends on it and can change it alongside. In this episode, I show you how to move computation without changing the API of the […]

“Temporal variables […] are useful only within their own routine, and thus they encourage long, complex routines” (Martin Fowler). Going down this path we decompose the statement-method further and then finally realize our HTML-statement without duplicating any computation! ► All Refactoring Episodes: http://goo.gl/f7Yf21 ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss […]

After breaking down the big statement method into smaller chunks it turns out that those chunks actually belong to the Rental class, so we move them over. Thanks to Eclipse’s intelligent move-refactoring assistant this is a pretty easy task! ► All Refactoring Episodes: http://goo.gl/f7Yf21 ► Let’s Develop! http://letsdeveloper.com ► Don’t […]

Ok, while task 1 was a soft introduction, task 2 ended up quite hard. It was more luck than anything that I had the right idea (and wikipedia to look up the formula). ► All CodeHunt Episodes: http://goo.gl/WtTJ3L ► Let’s Develop! http://letsdeveloper.com ► Don’t Miss an Episode: http://goo.gl/whzDi1 «CodeHunt» An […]
