Java Programming Basics

Subject : it-skills
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. Tests to see whether a certain object comes from a certain class.






2. Indicates that a value is either true or false in the Java sense.






3. Ends execution of a method and possibly returns a value to the calling code.






4. You can't use this word in a Java program. The word has no meaning. Because it's a keyword you can't create a goto variable.






5. A class that wraps primitives - Integer or Boolean...






6. A CORBA standard for building server-side applications that are portable across heterogeneous ORBs.






7. The core framework supports clocks for synchronizing between different media (e.g. audio and video output). The standard extension framework allows users to do full audio and video streaming.






8. Used to generate HTML






9. Creates a subclass






10. Servlet is: loaded by servlet container when 1st requested; is then forwarded the user's request; processes the user's request; returns the response back to the servlet container. Servlet container sends this response back to the user. Servlet stays






11. Indicates that a variable or method can be used only within a certain class.






12. A software "execution engine" that safely and compatibly executes the byte codes in Java class files on a microprocessor (whether in a computer or in another electronic device).






13. Indicates that a method doesn't return a value.






14. A description of the structure and properties of a class of XML files.






15. Two Servlet API packages: javax.servlet.* ___________






16. Introduces statements that are watched (during runtime) for things that can go wrong.






17. An opensource Java Application Server






18. Reuses the functionality from a previously defined interface.






19. A test suite - a set of tools and other requirements used to certify a Java platform implementation conformant both to the applicable Java platform specifications and to Java Software reference implementations.






20. Creates a new exception object and indicates that an exceptional situation (usually something unwanted) has occurred.






21. Introduces statements that are executed when the condition in an if statement isn't true.






22. Indicates that if and when an object is serialized a variable's value doesn't need to be stored.






23. Indicates that a value is a 64-bit whole number.






24. Creates an object from an existing class.






25. You can't use this word in a Java program. The word has no meaning. Because it's a keyword - you can't create a const variable.






26. A set of Java APIs that may be incorporated an optional package for any Java 2 Platform Edition. The Jini APIs enable transparent networking of devices and services and eliminates the need for system or network administration intervention by a user.






27. Imposes strict rules on the use of a variable by more than one thread at a time.






28. CRUD: Create - Retrieve - ________ - Delete






29. A distributed object model for Java program to Java program in which the methods of remote objects written in the Java programming language can be invoked from other Java virtual machines1 - possibly on different hosts.






30. A tool for checking compliance of applications and applets to a specification.






31. Indicates that the details of a class or a method or an interface are given elsewhere in the code.






32. A definition of the interfaces that permit CORBA objects to participate in transactions.






33. Used to terminate the execution of the current JSP page and switch control to another resource






34. Introduces a path of execution to take when no case is a match in a switch statement.






35. Introduces a class






36. Limits the computer's ability to represent extra large or extra small numbers when the computer does intermediate calculations on float and double values.






37. Enables the programmer to use code that was written in another language (one of those awful languages other than Java).






38. Type of Java program (as opposed to a stand-alone program) which is embedded in a web page (requested from a server) and run on a client-side browser






39. Includes a file in the page






40. A platform-independent file format that aggregates many files into one. Multiple applets written in the Java programming language and their requisite components (.class files & images & sounds and other resource files) can be bundled in a JAR file an






41. The output of one servlet act as a input to another servlet.






42. A special Java servlet-aware web server process.






43. A library than enables CORBA objects to locate and communicate with one another.






44. Basic code block of a JSP page






45. Consists of class libraries - a Java virtual machine (JVM) and class loader (which comprise the runtime environment) and a compiler - debugger and other tools (which comprise the development kit).






46. Tests to see whether a condition is true. If it's true the computer executes certain statements; otherwise the computer executes other statements.






47. A set of APIs that support the integration of audio and video clips & 2D fonts & graphics and images as well as 3D models and telephony.






48. _______ separates Java code/functionality from page design and use of tags in JSP and allows for re-use of beans






49. A technology that provides distributed persistence and data exchange mechanisms for code in Java.






50. Enables the programmer to abbreviate the names of classes defined in a package.
