Course Overview
- This course offers a highly focused and practical approach to mastering essential Java development concepts, specifically engineered to excel in technical interviews.
- Dive into the architecture and implementation of a real-world ‘Bank Customer Management System,’ providing invaluable context for enterprise-grade applications.
- Beyond syntax, gain a deeper understanding of ‘why’ certain patterns and practices are adopted in modern microservices development.
- Strategically structured to bridge the gap between academic knowledge and the expectations of a professional Java developer role.
- Learn to articulate complex technical ideas and design choices, which is crucial for succeeding in advanced interview stages.
- Experience the full development lifecycle, from initial setup and coding to testing and understanding project structure.
- Prepares you not just to answer questions, but to demonstrate actual problem-solving capabilities with a robust project example.
Requirements / Prerequisites
- A foundational understanding of basic programming principles and logical thinking.
- Familiarity with any object-oriented programming language is beneficial, though not strictly required for grasping the core OOPs concepts.
- Access to a personal computer (Windows, macOS, or Linux) with an active internet connection.
- Willingness to install necessary development tools like an IDE (e.g., IntelliJ IDEA, Eclipse) and MySQL Workbench (guidance will be provided).
- A strong desire to learn, practice coding, and engage with real-world project scenarios.
- No prior expertise in Spring Boot, Hibernate, JPA, or advanced SQL is expected, as these technologies are introduced.
