Which term describes a block of code that forms a class?

• A. Cursor
• B. Constructor
• C. Cookie
• D. CSRF

Answer: (B)

In object-oriented programming, a constructor is the special method inside a class that runs when a new object is created. It’s the block of code responsible for initializing the new instance, setting up its initial state by assigning values to fields and performing any setup the object needs. This is why it’s the best fit for describing the code that forms or builds an instance of a class—the routine that brings the class blueprint to life. The other terms don’t describe this role: a cursor is used to traverse data, typically in a database or editor; a cookie is data stored by a web browser; CSRF refers to a security vulnerability related to unauthorized requests.
