In Java, what is the blueprint from which objects are created?

• A. An interface
• B. A class
• C. A method
• D. A package

Answer: (B)

The blueprint for objects in Java is a class. A class defines the data an object can hold (fields) and the actions it can perform (methods), acting as a template that describes what each object will contain and be able to do. When you create a new instance with new, you’re building an object based on that class’s blueprint. An interface, while also important, describes a contract of methods that a class may implement and cannot be instantiated on its own. A method is a function inside a class that implements behavior, not a full object blueprint. A package is simply a way to organize related classes. So the class is the source from which objects are created.
