Fun with Objects and Classes

What is a class in programming?

• A class is a method used to manipulate strings.

• A class is a blueprint for creating objects that defines properties and methods.

• A class is a function that executes code.

• A class is a type of variable that stores data.

Can you name an object from your favorite toy?

• brick

• ball

• doll

• car

What do we call a special action that an object can do?

• method

• property

• attribute

• function

If a class is like a blueprint, what is an object?

• An object is a type of class.

• An object is a collection of classes.

• An object is an instance of a class.

• An object is a blueprint for a class.

How do we use an object in a program?

• You must delete an object after using it to free up memory.

• You define, instantiate, and interact with the object's properties and methods.

• You can only define an object without using its methods.

• Objects are used solely for storing data without any interaction.

What is a method in an object?

• A method is a type of object.

• A method is a function associated with an object.

• A method is a property of an object.

Can you think of a real-life object that has methods?

• A smartphone

• A bicycle

• A refrigerator

• A car

What happens when we call a method on an object?

• The method is ignored and has no effect on the object.

• The method is executed in the context of the object, accessing its properties and methods.

• The method is executed globally, affecting all objects of the same type.

• The method is executed but does not have access to the object's properties.

Why do we use classes to create objects?

• Classes are only used in programming languages that support inheritance.

• We use classes to create objects to encapsulate data and behavior, enabling code reusability and better organization.

• Classes are used to create objects for aesthetic purposes.

• Classes are a way to define global variables in a program.

Can you give an example of an object and its method?

• Phone: call()

• Car: drive()

• Bicycle: pedal()

• Computer: compute()
