Advance Concepts in JAVA - Notes By ShariqSP

Introduction to Various Programming Concepts

Welcome, students, to our programming class! Today, we'll delve into several important topics that are fundamental to understanding and implementing efficient and organized code.

Math Class

In programming, math is not only about arithmetic operations; it extends to various mathematical functions and algorithms used in software development. Understanding mathematical concepts is crucial for solving complex problems efficiently.

Garbage Collection

Garbage collection is a vital process in programming languages with automatic memory management. It deals with reclaiming memory occupied by objects that are no longer in use, thereby preventing memory leaks and optimizing memory usage.

Singleton Class

A singleton class is a design pattern that restricts the instantiation of a class to a single object. It ensures that only one instance of the class exists throughout the program and provides a global point of access to that instance.

File Handling

File handling involves performing operations on files, such as reading from or writing to them. It's essential for interacting with external data sources, storing configurations, and managing persistent data in applications.

Inner Classes

Inner classes, also known as nested classes, are classes defined within another class. They are useful for logically grouping classes and improving code organization, encapsulation, and access control.

Object Cloning

Object cloning refers to creating an exact copy of an existing object. It can be achieved either through shallow or deep copying, depending on whether references within the object are copied recursively or not.

Serialization and Deserialization

Serialization is the process of converting objects into a stream of bytes for storage or transmission. Deserialization is the reverse process of reconstructing objects from the serialized form. These techniques are essential for data persistence and inter-process communication.

Loose Coupling vs. Tight Coupling

Loose coupling refers to a design principle where components of a system are independent and interact through well-defined interfaces, reducing dependencies and enhancing flexibility and maintainability. In contrast, tight coupling implies strong interdependence between components, making the system less modular and harder to maintain.

Streams

Streams represent a sequence of elements that support various operations to perform computations efficiently. They are commonly used in functional programming paradigms for processing collections of data in a declarative manner.
