JavaSocket: A secret class in Java & nbsp; Socket programming, Javascript tutorial

Introduction

The Java platform implements Socket in the java.net package. In this article, we will use the following three classes in the Java.net package to work:

URLConnection
Socket
ServerSocket

There are more classes in the java.net package, but these are the most common ones. Let's start with URLConnection, this class provides the method of using Socket in your java code without understanding the underlying mechanism of Socket.

You can use sockets without even trying.

To connect to a URL, follow these steps:

Create a URLConnection

Configure it using different setter Methods

Connect to URLConnection

Interaction with different getter Methods

Next, we will use some examples to demonstrate how to use URLConnection to request a document from a server.

URLClient class

We will start with the structure of the URLClient class.

Import java. io .*;
Import java.net .*;
Public class URLClient {
Protected URLConnection connection;
Public static void main (String [] args ){}
Public String getDocumentAt (String urlString ){}
}

Note: you must first import the java.net and java. io packages.
