Java Socket Programming: Build a Chat Application

Create a simple client-server calculator using a server socket, port binding, buffered readers, and a print writer to exchange inputs and results.

Build a client-server calculator using sockets, buffered reader, and print writer; the client displays menu for addition, subtraction, multiplication, and division and sends numbers to the server, which returns result.

Explore a Java socket client-server application, where the server waits for connections, handles add, subtract, multiply, divide operations, and supports an exit option.

Build a multi-threaded Java socket chat server that listens on a port, accepts client connections, and handles each client with a dedicated thread using a buffered reader and print writer.

Build a swing-based chat gui with a chat area, a text field, and a send button in a frame wrapped by a scroll pane, enabling input only after server permission.

Learn how a Java socket chat server enforces unique usernames by maintaining username and print writer lists, validating input, and broadcasting accepted names.

Wire an action listener to the send button and enter key to send input via the socket output stream, and read and broadcast messages to all clients using print writers.

Add a name label to chat windows to show the logged-in user, using server name accepted parsing with starts with and substring to display you are logged in as name.

Practice java socket programming by modifying the chat application and adding new functionalities. Run the program to see the output and look forward to more courses.
