Question

Which of these class is used to create servers that listen for either local or remote client programs?

(a) httpServer

(b) ServerSockets

(c) MimeHeader

(d) HttpResponse

I got this question in an interview for internship.

This key question is from Networking in division Serialization & Networking of Java

Answer 1

The correct answer is:

(b) ServerSockets

Explanation:

• (a) httpServer: This is not a standard class in Java for creating servers. It may be confused with server functionalities in certain libraries, but it's not the correct answer.
• (b) ServerSockets: This is the correct class. ServerSocket in Java is used to create server applications that listen for client connections. It listens for incoming requests on a specific port and establishes a communication channel with remote or local clients.
• (c) MimeHeader: This class is not related to server creation. It's used for handling MIME headers in HTTP communication, not for setting up servers.
• (d) HttpResponse: This class represents the response in HTTP communication, not a server that listens for clients.

Thus, (b) ServerSockets is the correct class to create servers that listen for client connections in Java.
