Align your reading of the notes with Durga Sir's video lectures. Code the examples manually rather than simply copying and pasting them. : Backed by a resizable dynamic array

: Arrays are always treated as objects in Java, meaning they reside on the heap memory even if they store primitive data types.

: Providing a specific implementation in a subclass for a method already declared in its superclass. Runtime resolution is managed dynamically by the Java Virtual Machine (JVM) based on the actual object type at runtime. Abstraction Code the examples manually rather than simply copying

Declared with the abstract keyword. They can house both concrete methods (with bodies) and abstract methods (without bodies). They cannot be directly instantiated.

An array is an indexed collection of fixed-size, homogeneous data elements.
