Understanding Programming Methodologies: A Comprehensive Guide Introduction Programming methodologies define structured approaches to writing code, improving efficiency, maintainability, and scalability. Different methodologies provide distinct ways of thinking about problem-solving, organizing logic, and structuring applications. This blog explores various programming methodologies, their advantages, drawbacks, applications, and best use cases. 1. Procedural Programming Procedural programming follows a step-by-step approach where code is structured as procedures or functions. Characteristics: Based on the concept of procedure calls. Follows a linear, top-down execution model. Uses variables, loops, and control structures. Languages: C, Pascal, Fortran Sample Code (C): #include <stdio.h> void greet() { printf("Hello, World!\n"); } int main() { greet(); return 0; } Applications: Embedded systems (e.g., firmware, microcontrollers) Operating systems (e.g., Li...
Socket communication in Java enables communication between two endpoints over a network. There are two main types of sockets: TCP sockets and UDP sockets. Let's explain both types with examples: TCP Socket Communication: 1. **Server Side**: - The server creates a `ServerSocket` object to listen for incoming connections on a specific port. - When a client connects, the server accepts the connection and creates a `Socket` object to communicate with the client. - The server reads from and writes to the socket's input and output streams to communicate with the client. import java.io.*; import java.net.*; public class TCPServer { public static void main(String[] args) throws IOException { ServerSocket serverSocket = new ServerSocket(12345); System.out.println("Server started. Waiting for client..."); Socket clientSocket = serverSocket.accept(); ...
