Jaime Filipe Jorge and António Menezes Leitão. The Impact of Programming Languages in Code Cloning. In 1st Symposium on Languages, Applications and Technologies. Open Access Series in Informatics (OASIcs), Volume 21, pp. 107-122, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2012)


Code cloning is a duplication of source code fragments that frequently occurs in large software systems. Although different studies exist that evidence cloning benefits, several others expose its harmfulness, specifically upon inconsistent clone management. One important cause for the creation of software clones is the inherent abstraction capabilities and terseness of the programming language being used. This paper focuses on the features of two different programming languages, namely Java and Scala, and studies how different language constructs can induce or reduce code cloning. This study was further developed using our tool Kamino which provided clone detection and concrete values.
