Dynamic memory allocation in Java refers to the process of allocating memory for objects at runtime.
Dynamic memory allocation allows for objects to be created and destroyed during program execution.

A constant is a value that does not change during the execution of a program.
Constants are used to store values that remain the same throughout the program.
They are declared using the 'const' keyword in many programming languages.
Examples include mathematical constants like pi (3.14159) or physical constants like the speed of light (299,792,458 m/s).
Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.
Objects are instances of classes, which define the structure and behavior of the objects.
Encapsulation, inheritance, and polymorphism are key principles of object oriented programming.
