Which term refers to the creation of an object based on a class?

• A. Instantiation
• B. Integer
• C. If Else Statement
• D. Implementation

Answer: (A)

Instantiating an object from a class is the act of creating a concrete object based on that class. In object-oriented programming, a class is like a blueprint, and an object is a real, usable instance created from that blueprint. During instantiation, memory is allocated for the new object and its constructor is typically invoked to initialize its fields, setting up the object so you can call its methods and access its properties. This is different from declaring a data type like Integer, which represents a primitive or wrapper type rather than the process of creating an object; a control flow construct like an If Else Statement, which governs decision-making in code; or the broader idea of Implementation, which refers to providing the actual code that fulfills a contract or interface rather than the act of producing an instance.
