This course aims to engage learners with little or no programming experience to create Java programs. Participants are introduced to object-oriented programming concepts, terminology and syntax, and the steps required to create basic Java programs using the Alice and Eclipse interactive development environments. Hand-on practice enables learners to experience the power of computer programming.

The JavaTM programming language can be challenging for computer programmers with limited or no experience in object-oriented programming. To provide an easy introduction to Java, Alice is explored first in this course, so that fundamental principles and skills are established using 3D animations in a fun, visually rich environment.

When learners become familiar with the concepts of object-oriented programming, they can proceed with the Eclipse integrated development environment (IDE), which is widely used in computer programming. It contains a basic workspace and an extendable plug-in system for customising the environment.

The content and pace of the course is adapted to the age and needs of the learners.

Do you want to learn how to program desktop applications in Java, C language, C ++, CSharp (C #), PSeint, Visual Basic .NET, Macros in Excel?

Do you want to learn how to program mobile applications in App Inventor 2?

My teaching methodology is Project Based Learning (PBL).

In this way, to build an application, I will teach you that the really important thing before sitting down to code (by attempt and error) in front of the computer, is the analysis and design of the algorithm (which constitutes 90% of the success of the program to be implemented. ), for this, with an example from the real world, the construction process will be explained: 1. Example with data from the real world, 2. Collection of information on requirements (input data, calculations, output data), 3. Hierarchy of operators (mathematical formulas versus computational formulas), 4. Desk test on a spreadsheet, 5. Constants, variables and data types to use, 6. Algorithm construction, 7. Flowchart, 8. Desk test on paper, 9. Implementation of the algorithm in the chosen programming language, if it is in console mode, it is implemented directly, if it is in form mode, the user interface is drawn on paper (UX) first.

Python is the programming language these days. It is simple, nice and almost all modern applications use it. With Python, we can now create artificial intelligence models that reduce human effort and give us more accurate and reliable results. The Java and C languages are not lacking in importance, they also make it possible to create applications optimized in terms of RAM.

The composition of the course depends on the level of the student and his own objectives. The first session is a one-hour evaluation session which allows the diagnosis of the level and the needs of the student. From this diagnosis we establish together a program that we will follow during our course.

Generally the course allows the student to assimilate:
* Predefined Data Types & Variables;
* Conditional Structures & Loops;
* Functions ;
* Object-oriented programming (OOP);
* Digital engineering;
* An introduction to databases (Examples and uses)
* Relational Algebra
* LDD, LCD, LMD, LCT
* SQL queries (SELECT, UPDATE, ...)
* Creation of a database and automation of queries using the Python language
* Handling files (TXT, Excel, CSV, JSON, Word);
* Data science;
* Introduction and some applications of Artificial Intelligence.

I am waiting for you to start this adventure.

In my lessons, I start by understanding exactly what the student needs, taking time to empathize and identify his/her challenges. I then check the students' prior knowledge and readiness for the topic he/she wants to learn. From there, I explain the content step by step, making sure the student can follow each stage clearly. I use visual and interactive tools, such as a tablet, to make learning more engaging and easier to understand. By the end of the lesson, I always ensure the student’s needs have been met and that they feel confident moving forward.
