Learning objectives

  • Understand the concept of reflection in programming
  • Identify relevant use cases for reflection in different languages
  • Implement reflection mechanisms in Java, C#, and Python
  • Anticipate risks, limitations, and impacts on security and performance
  • Apply best practices for using reflection in professional projects

Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • 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.

Program

Module 1Fundamentals and Multi-Language Reflection

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.

Module 2Implementing Reflection: Java, C#, Python

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.

Module 3Security, Performance, and Production Best Practices

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.

Evaluation method

  • Case studies at the end of each module
  • Ongoing project with presentation
  • Final multiple-choice quiz

Learning method

  • Interactive courses illustrated with concrete examples
  • Live coding sessions
  • Hands-on exercises on dedicated environments
  • Complete materials provided at the end of the training

Methods, materials and delivery

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.

Equipment required

For the smooth delivery of the Training: Mastering Reflections in Programming: Fundamentals, Uses, and Best Practices program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

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.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training: Mastering Reflections in Programming: Fundamentals, Uses, and Best Practices program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

Training quality, guaranteed at every step

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
