18.3.2. TCP Client Example

Try these first

1. 1.

   What class is used to create a TCP socket in Java?

   Hint

   Think about the class that initiates the networking connection.

2. 2.

   What method is used to send data to the server?

   Hint

   Consider the method that sends a line of text.

3. 3.

   What does the PrintWriter class do in a TCP client?

   • A. Reads data from a socket
   • B. Sends data to a socket
   • C. Closes the connection

   Hint

   Focus on what action is associated with this class.

4. 4.

   True or False: A TCP client can transmit data without establishing a connection first.

   • True
   • False

   Hint

   Recall how TCP operates as a connection-oriented protocol.

5. 5.

   Modify the TCP client code to implement error handling when connecting to the server. What would this entail?

   Hint

   Think about what types of errors could occur when networking.

6. 6.

   Create a scenario where the client sends multiple messages to the server in a loop. How would you manage the socket connection?

   Hint

   Consider how you might structure your code to keep connections and data flowing seamlessly.
