This comprehensive Java Backend Developer Training is a 3-month, instructor-led online program designed to transform learners into industry-ready backend developers. Starting with Core Java, the course covers essential concepts like syntax, data types, control statements, arrays, loops, and OOP principles including inheritance, polymorphism, abstraction, and encapsulation. Students will master exception handling, the Collections Framework, Java 8 features like Streams and Lambdas, and File I/O operations. Advancing into backend development, the course dives deep into JDBC, MySQL/PostgreSQL database integration, and a full-stack introduction to the Spring Framework and Spring Boot. Participants will build RESTful web services, implement CRUD operations using Spring Data JPA, validate APIs, and document them using Swagger while testing with Postman. The training also includes Maven and Gradle for build automation. In the final phase, learners explore microservices architecture, including API Gateway, Service Discovery (Eureka), Spring Cloud Config, and basic Spring Security with JWT. Additionally, the course covers Docker for containerization and guides students through cloud deployment using AWS or Azure (EC2/Elastic Beanstalk). The program concludes with a capstone project, resume building, GitHub portfolio setup, and interview preparation, making it an ideal pathway for aspiring backend developers looking to enter the tech industry with confidence.
