Creating Ruby classes and instances

Creating a class

Objects are created from the class. Creating an object from a class is called instantiation.

We will actually create a class. Use the class syntax as follows:

sample.rb


class House
end

There is a rule to capitalize the beginning of the class name. With this description, I was able to define a minimal House class.

Instantiation

Next, we will create an instance (object) from the created House class. You can create an instance (object) by using the new method.

sample.rb


class House
end
House.new

To call a class, write the class name.

sample.rb


class House
end
House

Instance (object) class

Let's make sure the instance class is the House class.

sample.rb


class House
end

puts House.new.class

Execute sample.rb on the console, and if the output is as follows, the instance has been created correctly from the House class.

House
