The Influence of the Java Collection Framework on Overall Energy Consumption
This work addresses energy efficiency for Java developers, but it is incremental as it builds on existing JFC implementations.
The paper tackled the problem of energy consumption in Java programs by analyzing the Java Collection Framework (JFC) implementations, resulting in an energy optimization approach that achieved 6.2% energy savings in preliminary tests.
This paper presents a detailed study of the energy consumption of the different Java Collection Framework (JFC) implementations. For each method of an implementation in this framework, we present its energy consumption when handling different amounts of data. Knowing the greenest methods for each implementation, we present an energy optimization approach for Java programs: based on calls to JFC methods in the source code of a program, we select the greenest implementation. Finally, we present preliminary results of optimizing a set of Java programs where we obtained 6.2% energy savings.
