create a udp client in ruby

Here's an example code to create a UDP client in ruby:

main.rb
require 'socket'

# Define the target host and port
host = 'localhost'
port = 1234

# Create a UDP socket
socket = UDPSocket.new

# Send a message to the server
message = 'Hello, server!'
socket.send(message, 0, host, port)

# Wait for a response from the server
response, sender = socket.recvfrom(1024)
puts "Response from #{sender}: #{response}"

# Close the socket
socket.close

Explanation:

1. We begin by requiring the socket module which provides the networking functionality.

2. We define the target host and port that the client will connect to.

3. Create a new UDPSocket object.

4. Send a message to the server using the send method of the socket object. The 0 parameter is the flags parameter and is set to 0 by default.

5. Wait for a response from the server using the recvfrom method of the socket object. The 1024 parameter is the maximum number of bytes that can be received in a single operation.

6. Display the response received from the server and the sender details.

7. Close the socket using the close method.
