The practice of binding data (variables) and code (methods) together into a single unit (a class). Achieve this using getters and setters. Inheritance (IS-A Relationship)

Packages act as containers to group related classes and interfaces, preventing naming conflicts. The import statement brings external classes into scope. Durga Sir cautions against overusing static imports ( import static ), as they can reduce code readability by hiding the origin of static members. Access Modifiers

Identifiers are names used for classes, methods, variables, and labels. Java enforces strict rules:

Core Java covers Java fundamentals and standard library essentials for writing robust, object-oriented applications. Durga Sir's notes are a concise, exam- and interview-focused compilation emphasizing concepts, examples, and common pitfalls.

Exception handling is a robust framework designed to intercept runtime errors, preserving normal application execution flow.

One of the main reasons these notes are labeled "Top" is their historical alignment with the . Flow Control The "Core Java complete notes by

Names used for classes, methods, variables, and interfaces. Java is case-sensitive, and identifiers must follow strict alphanumeric rules without starting with a digit.

: Java does not support multiple inheritance with classes to avoid ambiguity problems (the "Diamond Problem"). It is achieved solely via interfaces. Polymorphism

: Java separates array declaration ( int[] arr; ) from creation ( arr = new int[5]; ).

The Streams API allows for declarative processing of data collections. It uses pipeline chains composed of intermediate operations (like filter() and map() ) and terminal operations (like collect() or forEach() ) to process data efficiently. Optional Class
