What you'll learn

Programming basic network applications

Programming client-server applications

TCP Sockets in Java

UDP Sockets in Java

Running multiple clients at the same time (multithreading)

Requirements

JDK (Java Development Kit) - you'll learn how to install it in the first lesson

Eclipse (code is same for other IDEs) - you'll learn how to install it in the first lesson

Basic Java knowledge would be nice, but not necessary

Basic understanding of computer networks (TCP/UDP)

Description

If you have a great idea for an app that needs to communicate through a network, or you're just beginning to learn Java, or you're a network engineer looking to implement one of many network protocols, you've come to the right place!

In this course, you'll get the tools to build both client-server and peer-to-peer applications. We'll cover both the use of TCP and UDP sockets, and I'll leave it to you to choose which one suits your application better. There are some bonus examples that you can use to practice, and you're more than welcome to post your questions, ideas or struggles in the Q&A section.

All of the code is thoroughly explained, so you don't need much prior Java knowledge, but basic understanding of programming in general is a plus.

Generally, network applications differ from non-network applications in their distributed nature, reliance on network protocols, client-server architecture, handling of network-related challenges, and utilization of web-based technologies. The networking aspect of these applications opens up opportunities for collaboration, remote access, and resource sharing, making them essential in today's interconnected world - which is why we'll learn about them in this course!

All feedback is welcome, so I encourage you to suggest ways to improve this course, but also criticize where needed. :) Hope you find it useful & learn something important here!
