5. 5 Instructional Philosophy Out-Come based education Would rather discuss than lecture –Requires student preparation Hate grading assignments –Especially LATE assignments Use class interaction, assignments, mini- quizzes and Capstone Project to determine if outcomes are met.

6. 6 Cos 260 Outcomes This course continues from the preliminary introduction to programming that is a core component of the prerequisite COS 111 Introduction to Computer Science course. Upon completion of this course, participants will have gained knowledge of object- oriented and structured programming paradigm concepts, principles, skills (including data type selection and implementation), and the ability to: effectively program in depth –effectively apply problem solving techniques to the design of computer algorithm(s) for a task –select the appropriate programming language(s) for a task –select and implement data type(s) most appropriate for a task (selected from arrays, records, stacks, queues, lists, simple trees) –test and debug programs –evaluate the quality and efficiency of a program –identify improvements that can be made to the quality and efficiency of a program's source code and/or documentation describe key programming concepts, including: –control structures –recursion –iteration –sorting –searching explain key social aspects of programming, including: –intellectual property –liability –privacy –ethical behavior 10/18/2015 6

19. 19 Objects and classes objects –represent ‘things’ from the real world, or from some problem domain (example: “the red car down there in the car park”) classes –represent all objects of a kind (example: “car”) Objects First with Java - A Practical Introduction using BlueJ, © David J.

21. 21 Methods and parameters Objects have operations which can be invoked (Java calls them methods). Methods may have parameters to pass additional information needed to execute. Objects First with Java - A Practical Introduction using BlueJ, © David J. Barnes, Michael Kölling

22. 22 Other observations Many instances can be created from a single class. An object has attributes: values stored in fields. The class defines what fields an object has, but each object stores its own set of values (the state of the object). Objects First with Java - A Practical Introduction using BlueJ, © David J.

26. 26 Source code Each class has source code (Java code) associated with it that defines its details (fields and methods). Objects First with Java - A Practical Introduction using BlueJ, © David J. Barnes, Michael Kölling

28. 28 Return values All the methods in the figures project have void return types; but … … methods may return a result via a return value. Such methods have a non- void return type.
