Core Java Complete Notes By Durga Sir

Introduction to Core Java

Core Java Topics

1. For Beginners: Do not read linearly. Use the notes as a companion to video lectures (available on YouTube). Watch a lecture, then review the corresponding note section.
2. For Interview Prep: Focus specifically on the "Differences" tables (e.g., ArrayList vs Vector, Checked vs Unchecked Exceptions) and the "FAQs" sections at the end of each module.
3. Skippable Content: Sections on AWT/Swing (legacy GUI) and Applets are outdated; prioritize Collections and Multithreading.

Modifiers:

11 words (e.g., public , static , final , abstract ).
