Object-oriented Programming

The course focuses on teaching the principles and techniques of object-oriented programming (OOP) using the Java and C++ languages. Students will gain knowledge of the syntax and semantics of the languages, learn to use basic data structures and implement algorithms, and become familiar with the concepts of class, object, inheritance, and polymorphism. At the same time, they will cultivate skills in software analysis, design, development, and evaluation, combining theory with practical application.

Upon successful completion of the course, the student will be able to:

Knowledge & Understanding

Understands the basic principles of object-oriented programming (OOP).

Knows the syntax and semantics of languages.

Recognizes basic data structures (arrays, lists, stacks, queues) and their management algorithms.

Understands the differences between procedural and object-oriented programming.

Application

Writes programs in Java/C++ using basic programming structures (variables, conditions, loops, functions).

Implements the object-oriented approach through classes, objects, methods and inheritance.

Develops simple applications that use files, dynamic memory management and exceptions.

Implements basic algorithms for sorting, searching and managing data.

Analysis & Synthesis

Analyzes problems and designs corresponding solutions using flowcharts and pseudocode.

Compares different programming techniques for optimal application performance.

Combines different data structures and methodologies to improve code efficiency.

Evaluation

Identifies and corrects errors (debugging) and performance issues in the code.

Judges the quality and maintainability of the code based on the principles of good programming practices.

Collaborates in software development teams using code management tools (e.g. Git).

Additional skills (Soft Skills & Metacognitive Skills)

Development of critical thinking and problem-solving skills.

Familiarity with self-directed learning and continuous updating of new developments in programming.
