About this product

These are the exact notes I used to prepare for my own Java interviews — not random notes copied from the internet. This is what actually got me the job.

What's inside:

  • Core Java
  • OOPs
  • Java 8
  • Collections
  • Spring Boot (from InterviewBit)
  • Microservices
  • DBMS
  • Design Principles

I've also added the exact websites and videos I used while preparing — so you don't have to waste time searching everywhere. Just click and go straight to the topic.

Notes are updated regularly, so you always get the current version — not something old sitting unused.

What are people saying

Excellent Java and Spring Boot notes! The content is clear, well structured, and easy to follow. Complex concepts are explained simply, making the notes very useful for learning, revision, and interview preparation. Great effort and highly recommended!
