OOPS concepts are fundamental to object-oriented programming. They include encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: bundling data and methods that operate on that data within a single unit.

• Inheritance: creating new classes from existing ones, inheriting their properties and methods.

• Polymorphism: the ability of objects to take on multiple forms, depending on the context.

• Abstraction: hidin...read more

Inheritance is a way to create new classes based on existing ones. ArrayList is a dynamic array implementation in Java.

• Inheritance allows a subclass to inherit properties and methods from a superclass.

• ArrayList operations include adding, removing, and accessing elements.

• Example of inheritance: class Dog extends Animal

• Example of ArrayList operation: myList.add(element)
