This podcast directly relates to our class as its main topic is Object Oriented Programming. The speaker starts off explaining that Object orientated programs are made of objects which interact with each other. These Programs are class based and in object oriented programming the objects are instances of the classes and their types are determined by said classes.

Many different coding languages are used in object oriented programming such as Java, and Python because they support object programming which the speaker says is in combination with procedural programming. Most languages that support object programming are multi paradigm and contain variables which store information in a lower amount of data types for example integers which can include strings or lists.

Methods used in object programming take inputs and generate outputs based on the data used which can be attributed to loops and conditionals. In object programming you can group methods into files (or modules) to help keep your program organized. The files or modules that you use will not conflict with methods or variables in a different file that may share the same name.

The languages that support object programming are known for using inheritance in order to reuse previous code (classes). Classes contain the methods and data used in the code and they also contain class functions including the classes objects and instances. According to the podcasts author objects can at times correspond to things in the real world, the example he uses is when a graphics program uses shapes like circles or squares or when a shopping website uses a “shopping cart”. While some objects represent things relating to the real world other objects represent things that are more abstract like a file or a translation of some sort.

Object programming is based on the concept of objects and the data they contain whether it be methods, data fields, etc. If you use an object to organize unlike classes that is not object oriented programming, you are meant to use objects to organize data that has similarities. An object being an instance of a class will contain methods which contain variables, the variables in objects still belong to the class and can also be called class variables.

Class methods only have access to variables contained in the class but there can also be instance methods which like instance variables belong to an object and they only have access to the instance variables for the specific object. Objects can be called upon by the code using the method and parameters for the object, you must call a constructor to call upon an object. In some languages objects can be composed by using traits, class based languages instantiate the objects with the classes while in prototype languages there are no classes and objects are their own entities. The Podcast explains the basics of Object Oriented Programming and the different languages and components used.
