“…Whereas static methods are used for function declaration outside classes in Java, Kotlin allows the declaration of function outside the classes. The approach in Java results in classes whose instances are never created, and static methods are called instead (Gotseva et al, 2019). The main feature of Kotlin is the support for non-nullable types, making applications less susceptible to the so-called null point dereference, i.e.…”

“…Similarly, when accessing an object of nullable types, the question-mark operator is used instead of the dot operator. An overview of data types in both languages is summarized in Table 1 (Gotseva et al, 2019). In addition, primitive and reference data types are differently organized in the memory.…”

“…However, in Kotlin, a primary constructor exists, which is declared outside the class body, while other constructors which are therefore secondary are declared in the class body. The role of the primary constructor is to initialize the class, while the secondary constructor(s) help to include additional logic while initializing the class (Gotseva et al, 2019). A more detailed analysis of the similarities and differences can be found in (Gotseva et al, 2019), where the authors highlight not only data types, but also operations and expressions, main statements, functions and subroutines, and a more detailed comparison in classes and objects.…”

With the recent rise of the Kotlin programming language as the main contender for Android mobile development, very few courses in Higher Education Institutions exist which incorporate Kotlin as one of the main languages. In addition, various online course platforms which offer learning Kotlin are still very low in number, and the ones that do exist are expensive. In this paper, an e-learning framework for the Kotlin programming language is presented, supporting automatic grading of given assessments. This framework is aimed at students who already have basic knowledge of Java (or similar) programming languages, and want to switch to mobile development. The solution focuses on the development of an interactive course in Kotlin. Furthermore, to compare our solution with commercially available ones, we point out the disadvantages of currently available Kotlin courses, such as the level of previous knowledge needed, or a need for a specific development environment.

“…Since Kotlin has 100% interoperability with Java, quite a few Kotlin related studies did a comparative study between Java and Kotlin language [7][8] [9]. They concluded that Kotlin is concise and safe, can improve the productivity of the programmer, and also improve the quality of applications.…”

Kotlin is a modern JVM language, gaining adoption rapidly and becoming Android official programming language. With its widely usage, the need for code analysis of Kotlin is increasing. Exposing code semantics explicitly with a properly structured format is the first step in code analysis and the construction of such representation is the foundation for downstream tasks. Recently, graph-based approaches become a promising way for encoding source code semantics. However, current works mainly focus on representation learning with limited interpretability and shallow domain knowledge. The known evolvements of code semantics in new-generation programming languages have been overlooked. How to establish an effective mapping between naturally concise Kotlin source code with graph-based representation needs to be studied by analyzing known language features. In this paper, we propose a first-sight, rule-based mapping method, using composite representation with AST, CFG, DFG, and language features. We evaluate mapping strategies with ablation experiments by simulating a code search solution as a downstream task. Our graph-based method with built-in language features outperforms the text-based way without introducing greater complexity. By addressing the practical barriers to extracting and exposing the hidden semantics from Kotlin source code, our study also helps enlighten source code representations for other modern languages.
