Learning outcomes

The course aims to provide an in-depth concptual & practical knowedlge about the basics concepts, methodologies, technologies and tools for the design and development of medium-size applications according to the object-oriented paradigm.

At the end, the student:

- knows the methodological foundations for the analysis and development of object-oriented software applications

- knows the corresponding techniques in depth both from the conceptual and practical viewpoints

- is able to apply such knowledge and techniques to medium-size applications using the Java language

- knows in depth the fundamental data structures and related algorithms

- has the fundamental notions of functional programming in modern OO-blended languages (Java, Kotlin, Scala, C#)

-is able to develop simple graphical user interfaces in JavaFX according to the event-driven programming pattern

Throughout the course, while the Java language and platform are the main reference (and the only one required for assessment in the final examination), a multi-language approach is adopted when introducing concepts and constructs, presenting the Java approch in comparison with other object-oriented languages such as C#, Scala, Kotlin, so as to provide a broader view.

 

Course contents

Basic concepts of programming languages. Language families -- imperative, functional, logic, and object-oriented languages (5hrs).

Introduction to software design: software components, abstract data types, objects. Basic concepts of the Java language and architecture: classes, instances, object construction and deletion, inheritance, polymorphism. Abstract classes, interfaces, multiple inheritance. (30hrs + 12hrs lab)

Lambda expressions and functional interfaces. (12hrs + 6hrs lab)

Exceptions and exception handling. I/O streams and file access, object serialization. Data structures: lists, hashmaps, trees and related algorithms. (20hrs + 12hrs lab)

Introduction to Java operation streams. (3rhs)

Basic elements for GUI construction in Java on the JavaFX platform: event-driven programming, event listeners. (10hrs + 10hrs lab)

Readings/Bibliography

Teaching methods

Slides (available from the VirtuaLE.unibo.it site) are discussed during class hours, avoiding students the burden of  taking notes so as to let them focus on the discussed concepts.

Exercises are continuously interleaved with theoretical concepts and immediately shown 'on line'. MS Teams is also exploited for blended learning, and to support team work during lab hours.

The theorectical module is strictly integrated with the parallel lab module, which is mainly devoted to lab experiments and exercises, both in groups and as individual activities: each week, a task is assigned to be completed during the lab session. Its resolution tests the students' ability in the concepts explained in the previous weeks, according to the constructive, "how to", interactive learning approach.

Due to the relevant lab work expected, this course requires the mandatory previous participation to both 1 & 2 modules about safety at work, as per the Italian law. Such modules can be attended on-line at [https://elearning-sicurezza.unibo.it/].

Assessment methods

Assessment is achieved both as self-evaluation in the lab sessions systematically proposed during the course, and as a final examination, which is integrated for both modules (theory & lab). The lab assignments during the course do not replace the final examination, nor do they contribute to the final evaluation, given their purpose of allowing students to self-evaluate.

The final examination consists in the practical implementation of the solution to a practical medium-size problem in the lab: during the test, students can freely consult books, manuals, on-line slides and resources in order to provide a solution to the proposed application problem. The test is divided in parts, with specific scores for each part, so as to effectively support student self-evaluation. 

The solution can be considered for correction and evaluation only if it is compiled by the Java compiler: if compilation fails, the test is not passed, regardless of any other consideration. If it compiles, the proposed solution is evaluated, taking into account in particular its conformity to the problem specification.

Specific rules for online exams are available both on the course web page and on Unibo VirtuaLE site.

Normally, a successful lab test (evaluation of 18/30 or above) can be officially registered as a passed exam. However, the teacher reserves the right to call the student to an oral discussion, which is mainly (but not exclusively) devoted to discuss the approach and solution of the lab test.

The student can always ask to take an optional oral exam, in order to (hopefully) improve his/her evaluation. In this case, the discussion concerns any topic in the course, and the final result is always officially registered.

Teaching tools

The main tools are the JDK (Java Development Kit) and the Eclipse IDE for Java developers; programming editors can also be of help for quick tests, as well as online testing environments (both for Java and other languages like Kotlin, Scala, C#) on a personal basis.

The course web pages provide updated information, while the VirtuaLE unibo site hosts all the course material (slides, exercises, start kits, extramaterial, suggested books).
