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(); System.out.println("Client connected."); BufferedReader in = new Bu

Introduction :
The course introduces Java language's syntax and
object-oriented programming paradigms from the perspective of Java language.
Further, the course thoroughly touches upon the vital aspects of the usage of
Java runtime library packages' classes and methods.
-------------------------------------------------------------------------------------------------------------------------
Course Outcomes :
At the end of this course students will be able to
1. Implement Object Oriented Programming paradigm using Java
language.
2. Exhibit the ability to use Java runtime library APIs to
provide a solution to a given problem.
3. Test and debug a Java program for a given problem.

ISE Evaluation: ISE Evaluation
for the course will consist of three programming (hands on) tests.
-------------------------------------------------------------------------------------------------------------------------
Internal Continuous Assessment
(ICA):
ICA shall consist of minimum 15
practical assignment problems.
The assignments should test and
develop student’s practical proficiency and ability to use Java API
Classes correctly for writing
code for varied applications scenarios & use case requirements.
Use of IDEs like BlueJ, Eclipse,
Netbeans or any other FOSS alternative for Interactive development
and debugging of Java
applications is highly recommend to enhance hands on skills in Java
Programming of Students.
