How Green Are Java Best Coding Practices?

Jérôme Rocheteau, Virginie Gaillard, Lamya Belhaj


This paper aims at explaining both how to measure energy consumption of Java source codes and what kind of conclusions can be drawn of these measures. This paper provides a formalization of best coding practices with a semantics based on quantitative metrics that correspond to the time, memory and energy saved while applying best coding practices. This paper also explains how to measure such source codes in order to provide repeatable and stable measures by combining both physical and logical sensors.
