03:15:00 In this video, the instructor explains how to create a class in Ruby, which is a custom data type that allows you to model real world objects.
03:20:00 In this tutorial, the author demonstrates how to make creating objects for a Ruby class easier by using the initialize method. This method allows you to set the class's attributes automatically when an object is created.
03:25:00 In this video, Ruby programming language instructor John Patterson demonstrates how to use an "initialize method" to give objects specific information (such as the title, author, and number of pages of a book) when they are created. This method saves time in coding because each time an object is created, the initialize method is called, automatically assigning the appropriate values.
03:30:00 This video tutorial explains how to create an instance method in Ruby, called "has honors". This method checks to see if the object calling the method has honors, and returns true or false depending on the result.
03:35:00 This video tutorial covers how to create a multiple choice quiz in Ruby using methods and classes. The instructor starts by discussing some of the pre-existing code that he has already written, including questions for a multiple choice quiz. He then creates a new question object and assigns it to the questions array. He creates another question object and assigns it to the prompt array, and then creates an initialize method for the question object. He creates questions for the prompt arrays p one, p two, and p three, and then creates an output statement to display the questions and answers. He also creates an instance of the question class and sets the prompt and answer for the new question.
03:40:00 This 1-paragraph summary explains how to run a Ruby programming test using a method that accepts an array of questions. The questions are asked to the user and their answers are stored in an answer variable. The test is scored and the user's score is printed at the end.
