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






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






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






4. An objects sense of direction.






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






6. When an object unintentionally overlaps with another.






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






8. 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.






9. Errors in the syntax of a computer program.






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






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






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






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






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






15. All objects have which two characteristics?






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






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






18. An object of a class.






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






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






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






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






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






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






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






26. A keyword that indicates that a new object is being created.






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






28. More specific types of a class.






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






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






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






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






33. Programming that allows the programmer to manipulate objects.






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






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






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






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






38. A type of item stored in an array - such as a string or integer - accessed using an index.






39. 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.






40. Describes the class's properties.






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






42. 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.






43. An error or break in a software program.






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






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






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






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






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






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






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