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

public static void main(String[] args) {
// Variables
int num1 = 10;
int num2 = 5;
// Arithmetic Operators
int sum = num1 + num2;
int difference = num1 - num2;
int product = num1 * num2;
int quotient = num1 / num2;
int remainder = num1 % num2;
// Comparison Operators
boolean isEqual = num1 == num2;
boolean isNotEqual = num1 != num2;
boolean isGreater = num1 > num2;
boolean isLess = num1 < num2;
boolean isGreaterOrEqual = num1 >= num2;
boolean isLessOrEqual = num1 <= num2;
// Logical Operators
boolean logicalAnd = (num1 > 0) && (num2 < 10);
boolean logicalOr = (num1 > 0) || (num2 < 10);
boolean logicalNot = !(num1 == num2);
// Conditional Statements
if (num1 > num2) {
System.out.println("num1 is greater than num2");
} else if (num1 < num2) {
System.out.println("num1 is less than num2");
} else {
System.out.println("num1 is equal to num2");
}
// Looping Statements
System.out.println("Printing numbers from 1 to 5:");
for (int i = 1; i <= 5; i++) {
System.out.print(i + " ");
}
System.out.println(); // Move to the next line
// Switch Statement
int dayOfWeek = 3;
String dayName;
switch (dayOfWeek) {
case 1:
dayName = "Sunday";
break;
case 2:
dayName = "Monday";

____________________
This program showcases the usage of variables (num1, num2), arithmetic operators (+, -, *, /, %), comparison operators (==, !=, >, <, >=, <=), logical operators (&&, ||, !), conditional statements (if, else if, else), looping statements (for loop), and the switch statement. It demonstrates basic operations and control flow in Java.
