The course consists of two parts. In the first, object-oriented programming in Java and the Test-based program development methodology are introduced. In the second part, functional programming is introduced using the Python language.

The goal of this teaching is to know the theoretical foundations of object-oriented and functional programming. The student that passes the exam are supposed: - to model an application by identifying the components and the best paradigm for their description; - to design and implement the chosen solution using both Java and Python; - to perform tests with Junit; - to master the Java and Python Collections framework; - to be able to recognize and manage non-standard cases through exception.

Formal prerequisites: passing grade in the Programming 1 and 2 courses.
Substantial prerequisites: mastering the principles of imperative programming.

Lectures that introduce theoretical concepts and laboratory exercises that apply them. In the lessons, theoretical topics are addressed through slide presentations, with examples and some questions to verify students' learning. In laboratory exercises, students are guided in the implementation of simple projects aimed at putting into practice the theoretical knowledge acquired.

The student is presented with weekly exercises (optional), which solution is started during the lab sessions and that should be completed by the student. The exercises are discussed and corrected both individually and in the classroom. The final tests (described in " Assesment methods") assess the student autonomy with respect to the design, implementation and testing of object-oriented programs implemented in Java.

The exam consists of two parts: a written exam on the theoretical and practical principles of functional and object-oriented programming; and the discussion of a more complex project carried out in Java. The written exam is aimed at verifying the concepts presented in class, respectively on the topics of object-oriented programming and functional programming and must be passed before the discussion of the project. The written exam consists of 4 questions/exercises on the OO part and 4 questions/exercises on the functional part. During the lessons, examples of the exercises that will be assigned during the exam will be show cased. The minimum threshold to pass the written exam is to answer correctly and completely to at least half of the questions/exercises. The written exam is worth 65% of the overall grade. The oral discussion will be sustainable only after having passed the minimum threshold in the written exam and requires the completion of a personal or group project aimed at verifying both the ability to structure a problem and its implementation with the use of Java libraries. The project (submitted before the test) is discussed during an oral exam and is worth 35% of the overall grade. The final grade is determined collegially, taking into account the grades of the two tests.

Knowledge and understanding: familiarity with the principles of object oriented and functional programming, the model/view/controller architecture and the methodologies for software testing.

Applying knowledge and understanding: ability to design and implement a project using object programming tools, with the specific Java language, and functional programming tools, with Python language, and deriving code from tests.

Making judgments: ability to recognize 1) good and bad programming practices, 2) when a programming paradigm is appropriate and 3) to evaluate the architectural quality of a project.

Communication Skills: mastering the specific terminology of object programming and functional programming and improving teamwork skills.

Learning Skills: ability to learn autonomously the use of other languages and other object oriented and/or functionally structured libraries.
