Chapter 4 ▪ Networking

We begin this chapter by reviewing basic networking concepts, then move on to writing Java programs that connect to network services. We will show you how network clients and servers are implemented. Finally, you will see how to send e-mail from a Java program and how to harvest information from a web server.

4.1. Connecting to a Server

In the following sections, you will connect to a server, first by hand and with telnet, and then with a Java program.

4.1.1. Using Telnet

The telnet program is a great debugging tool for network programming. You should be able to launch it by typing telnet from a command shell.

In Windows, you need to activate telnet. Go to the Control Panel, select Programs, click Turn Windows ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
