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






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






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






4. A systematic process for determining user expectations.






5. 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.






6. 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.






7. When an object unintentionally overlaps with another.






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






9. Process of finding and removing bugs—or errors—in a computer program.






10. Errors in the syntax of a computer program.






11. Control structure that allows you to execute specific sections of the code a number of times.






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






13. Defines what all instances of each class are capable of doing. The behavior of each instance is determined by the source code of its class.






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






15. This control performs a process while a condition is true; otherwise it will stop the instructions.






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






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






18. Describes the class's properties.






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






20. All objects have which two characteristics?






21. A defined start and end point in a quality assurance program.






22. A process to identify and remove repetitive programming statements from a main program - and put them into their own procedure.






23. An objects sense of direction.






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






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






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






27. Detailed - ordered list of the actions each object performs in each scene of the animation.






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






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






30. An object of the class.






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






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






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






34. Describes how to perform the procedure.






35. Notes that help other programmers understand what your program does.






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






37. More specific types of a class.






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






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






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






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






42. Answers questions about an object - such as its distance to another object.






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






44. Access - return type - name - and parameters for a method.






45. A list of actions to perform a task or solve a problem.






46. The specifications that define the appearance and movement of a 3D object.






47. This control performs a process if a condition is true; otherwise it performs another process.






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






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






50. A special kind of method that is automatically executed whenever a new instance of the class is created.
