Basics of Socket Programming in Java

3/19/2019
During such a situation they often seek Socket Programming assignment help from subject experts to complete their academic tasks.

Ever heard about Java socket programming? Well, in the Java concept, the term socket refers to the end-point of the two-way communication between two different programs running on the same network. As we already know that every server is the program that runs on a particular system and listens to the selected port. Generally, the socket is bound to the port to ensure that TCP port can identify the application which is destined to be sent. Students who write an assignment on the Java socket programming often find themselves at lost as they could understand the basic concept of the socket programming. During such a situation they often seek assignment writing help on Socket Programming from subject experts to complete their academic tasks.

The Basic Concept of the Socket Programming

As mentioned above the socket-programming establishes the connection between applications that are running on the different JRE. There are basically two types of socket programming namely; connection-less and connection-oriented.

While socket and server socket classes are mainly used to establish the connection-oriented programming, the connection-oriented take Datagram Packet and Datagram Socket classes. As a beginner who is dealing with socket programming, you should know two main important information:

What is the Socket Class?

The socket class refers to the endpoint between different machines. A predefined set of socket classes can be used to create a socket.

There are three basic methods that can be used to establish the socket class:

What is the Server Socket Class?

Similar to the socket class, it requires the pre-defined set class to create the Server Socket. But opposite to the socket class, the server socket is used to establish positive communication with clients. There are two important methods to create the server socket:

Let’s take a look at the example of Java socket programming in which a client has sent a text to the server.

MyServer.java

import java.io.*;import java.net.*;public class MyServer {public static void main(String[] args){try{ServerSocket ss=new ServerSocket(6666);Socket s=ss.accept();//establishes connectionDataInputStream dis=new DataInputStream(s.getInputStream());String 

System.out.println("message= "+str);ss.close();}catch(Exception e){System.out.println(e);}}}MyClient.java

import java.io.*

import java.net.*;

public class MyClient {

public static void main(String[] args) {

try{

Socket s=new Socket("localhost",6666);

DataOutputStream dout=new DataOutputStream(s.getOutputStream());

dout.writeUTF("Hello Server");

dout.flush();

dout.close();

s.close();

}catch(Exception e){System.out.println(e);}

}

}

Major pitfall of the socket programming

Programmers ignore return status: This is one of the most common pitfalls a programmer faces while writing the socket program. Ignoring the return status can cause loss of track of the program failure and success.

Address error: Most of the programmer use “bind” API function to bind the address in socket. The main problem with the bind is that programmers often use bind as an attempt to bind that port that is already use.

Binary data can complicate things: Socket are just the perfect unstructured binary data but when you try to send structured data through the socket the process become much more complicated.
