A Client$/$Server Project

This project presents a client program and a server program. The client sends data to a server. The server receives the data, uses it to produce a result, and then sends the result back to the client. The client displays the result on the console. In this example, the data sent from the client comprises the radius of a circle, and the result produced by the server is the area of the circle $($see Figure below$).$

The client sends the radius to the server; the server computes the area and sends it to the client.

The client sends the radius through a DataOutputStream on the output stream socket, and the server receives the radius through the DataInputStream on the input stream socket, as shown in Figure below $($a$).$ The server computes the area and sends it to the client through a DataOutputStream on the output stream socket, and the client receives the area through a DataInputStream on the input stream socket, as shown in Figure below $($b$).$

$($a$)$ The client sends the radius to the server. $($b$)$ The server sends the area to the client.

The figure below contains a sample run of the server and the client.

The client sends the radius to the server. The server receives it$,$ computes the area, and sends the area to the client.
