Title: Improving Java Performance With Native Libraries
Authors: Seppälä, Niklas
Publication Year: 2024
Collection: Theseus.fi (Open Repository of the Universities of Applied Sciences / Ammattikorkeakoulujen julkaisuarkisto)
Subject Terms: Mobile Solutions, fi=Tieto- ja viestintätekniikka|sv=Informations- och kommunikationsteknik|en=Information and Communications Technology, Java, libraries, programming, computer programmes, applications (computer programmes), Java SE, Tieto- ja viestintätekniikan tutkinto-ohjelma
Description: The purpose of this thesis was to conduct in-depth research into available solutions for interfacing with native libraries from Java program, trying to identify the best solution for different situations. The study focused on JNI, JNA, and FFM API. The research was conducted for Profium. The research relied heavily on Java language specifications and API documentations for source material, and supplementary benchmarks were created for comparing the different foreign function solutions in practice. Benchmarks evaluated Java wrapper objects utilizing indexing library implemented in C programming language. The outcome of this thesis was that while native libraries can be used to improve performance, it is not always required. The first step should be to find bottlenecks in existing Java code and to try optimizing it. Utilizing native functions is most suitable for larger computing tasks, which do not require communication back and forth between Java and native code.
