Learning Outcome

At the end of this lesson, you will be able to:

• understand and create a basic class, then create an object from the class

Review

• structured programming

  • Functional Programming: only use items passed into it and have a return value(s)

• History of Object Oriented Programming

  • around 1965, super recent!

Lesson

• read "Using OOP", Chapter 8, Computer Based Problem Solving

  • read "What is an Object"

Activity

• go over Bicycle Class example:

  • Bicycle Example - TypeScript

  • Bicycle Example - Java

• read over what a "Stack" is

  • you can also look at this and this for help

  • see python example

Daily Assignment

• consider a basic 3-number combination lock

  • taking into account what you read above, answer (on today's page) each of the questions that follow?

    • What is the lock's function?

    • Keeping in mind your answer to question number 1, what properties or characteristics would you use to describe the lock?

    • Describe the lock's behaviours - again, keep in mind what the function of the lock is and how it would perform that function?

• re-create the MrCoxallStack:

  • we will continue to improve it over several days

  • make sure the "MrCoxallStack" class is in a separate file from the use of the stack class (your main)

  • ENSURE you include correct DocStrings as comments:

    • JSDocs

    • Java Docs

  • for now, make your class implement pushItem(stringItem) and showStack() -> stringValues

  • make your stub program just create a stack instance at this point and then use the "push" method

  • you will get some Linting errors for Java, that is OK for now

    • we will learn why shortly!

    • see below

Extra

• do the above in a second language
