Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The specifications that define the appearance and movement of a 3D object.






2. An object that holds multiple variables. An index can be used to access the variables.






3. Errors in the syntax of a computer program.






4. When an object unintentionally overlaps with another.






5. A set of data with values having predefined characteristics.






6. A set of instructions - or programmed code - for how the object should perform a task.






7. Word at the beginning of the method that tells us what type of information a method call will return.






8. Series of illustrated images that represent the main scenes in the animation.






9. Applying the same test case to many parts of a software program.






10. Called a 'requirements specification' in computing - this is a story in the form of a problem to solve or task to perform.






11. Control structure that allows you to select specific sections of code to be executed.






12. This allows the programmer to adjust the object - motion - distance amount and time duration.






13. A list of instructions that are required to accomplish a task.






14. Used to pass values to methods to specify how objects are to move - or to tell objects what type of response we expect when we ask objects a question.






15. A statement that can execute a section of code multiple times.






16. Symbols that can be used to combine multiple boolean expressions into one boolean expression.






17. The process of finding software bugs in a software program






18. Describes the class's properties.






19. Each subclass receives the methods and properties of its superclass.






20. A technique that allows a class to use a method from another class or object. The dot between the class/object name and the method name indicates that the method comes from a different class or object.






21. The systematic process of checking to see whether a product being developed is meeting specified requirements.






22. A technique used to command newly-created instances to perform different actions.






23. Each subclass can use (inherits) the methods from its superclass.






24. A lexical unit used to perform basic mathematical operations by taking two operands and returning the result of the mathematical calculation.






25. Set of operations or tasks that instances of a class can perform. When a method is invoked - it will perform the operation or task specified in the source code.






26. An object from a class once its created and added to the scene.






27. Tell Alice3 how to implement the instructions in a program.






28. An error or break in a software program.






29. A piece of code that sends a message to an object asking it to perform an action.






30. The template that defines the substance of an object - such as its appearance - features - and movement.






31. A software tool used by computer programmers to develop software applications that includes tools for writing - editing - compiling - deploying - and debugging programs.






32. A piece of program code that defines how the object should execute a task.






33. A loop that causes the code to keep executing. The code does not stop because the end to the code isn't established.






34. Notes that help other programmers understand what the code in your program does.






35. Symbols that compare two random values in a method.






36. A variable declared inside the body of the method to temporarily store values - such as references to objects or integers.






37. Tell the objects in the animation how to perform tasks.






38. A position number in the array object that specifies which array element to access.






39. Translates the source code into a machine code that the computer can understand. This ensures that you added the source code or class correctly before you proceed.






40. The more generic - overarching class of a group of classes.






41. A method call instructs the instance to perform an operation ortask. You can read the method to understand what operation or task is to be performed.






42. A specification - such as a blueprint or pattern and a set of instructions - of how to construct something.






43. A field used to store information about the class to use immediately or later.






44. A place in memory where data of a specific type can be stored for later retrieval and use.






45. The memory that the instance of the class has. That memory can be saved and accessed later as long as the instance exists.






46. The general set of instructions and rules that objects will follow.






47. A set of conditions or variables with which a test engineer will determine if a software program is working correctly.






48. An object of a class.






49. An object's sense of direction.






50. An object of the class.
