Don't let this gap widen
Without mastery of reflection in object-oriented programming languages, your applications accumulate insidious bugs and critical security vulnerabilities, making the code fragile and unmanageable.
Teams lose an average of 30% of their development time on complex debugging, equivalent to 50 000 € in wasted productivity per annual project.
25% of production incidents at tech companies are linked to improper use of reflection, with remediation costs exceeding 100 000 € per breach.
Every delay exposes your company to a loss of competitiveness and threatens your advancement as an architect or senior engineer.
Introduction to concepts: introspection, metaprogrammation, dynamic versus static. Overview of the history and main uses of reflection. First examples in Java, C#, and Python. Critical analysis of advantages and disadvantages.
In-depth study of reflection APIs: java.lang.reflect, System.Reflection, Python's inspect module. Manipulation of objects, classes, attributes, methods, and annotations at runtime. Dynamic creation of instances, method invocation, and field modification. Concrete cases: serialization, object mocking, plugin loading.
Analysis of security risks related to reflection (sandboxing, injection attacks, implementation leaks). Performance impacts and monitoring tools. Implementation of patterns and strategies to limit usage (Proxy, Factory, Dependency Injection). Real-world experience feedback. Group workshop: audit and refactoring of an existing project using reflection.
The Training: Mastering Reflections in Programming: Fundamentals, Uses, and Best Practices program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.
For the smooth delivery of the Training: Mastering Reflections in Programming: Fundamentals, Uses, and Best Practices program, the following equipment is required:
For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
