When we wish to initialize some class variables at the moment of object creation, we can utilize the initialize method. The initialize function is part of Ruby's object-creation process, and it allows us to set an object's initial properties. Here are some things to think about when it comes to Initialize: We have the option of defining a default parameter.

The first crucial thing to remember is that in Ruby, the method initialize is a special method with a special meaning: When you call a class's new method, such as Person.new, the class creates a new instance of itself. It will then call the function initialize on the new object internally.

Before they may be utilized in method declarations, class variables begin with @@ and must be initialized. An error occurs when a class variable is referenced that has not been initialized. The descendants of the class or module in which the class variables are specified share the class variables.

  • An initialize method should always be defined in a class or module. It should always have one parameter and it should always return a value. This value can be whatever you want, but it usually returns nil as you don't want to do anything else before your methods are run.
  • An example of an initialize method would look like this: def my_table_class(name)
  • # Set
