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. Gets the computer to repeat some statements over and over again (for instance a certain number of times).






2. Useful only for small sites






3. Includes a file in the page






4. Indicates that a method or constructor may pass the buck when an exception is thrown.






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






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






7. Includes a new tag library into page - allows use of tags in page






8. A Web scripting language that is used in both browsers and Web servers. Like all scripting languages it is used primarily to tie other components together or to accept user input.






9. A software development environment for writing applets and application in Java .






10. An extension that adds graphical user interface class libraries to the Abstract Windowing Toolkit (AWT).






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






12. A standard programming interface for writing Java native methods and embedding the JVM into native applications. The primary goal is binary compatibility of native method libraries across all JVM implementations on a given platform.






13. Creates a subclass






14. A protocol used for communication between CORBA object request brokers.






15. Indicates that a variable or class or method can be used by any other Java code.






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






17. Introduces an interface which is like a class but less specific.






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






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






20. 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.






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






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






23. Sets attributes and properties specific to the current JSP page






24. CRUD: Create - Retrieve - ________ - Delete






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






26. 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.






27. Indicates that a value is a 16-bit whole number.






28. Causes the computer to repeat some statements over and over again (for instance as long as the computer keeps getting unacceptable results).






29. Creates a newly defined type






30. A set of APIs that assists with the interfacing to multiple naming and directory services.






31. Reuses the functionality from a previously defined interface.






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






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






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






35. Indicates that a variable or method belongs to a class rather than to any object created from the class.






36. Puts the code into a package






37. An opensource Java Application Server






38. Creates an object from an existing class.






39. An industry standard for database-independent connectivity between the Java platform and a wide range of databases. The JDBC provides a call-level API for SQL-based database access.






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






41. A tree of objects with interfaces for traversing the tree and writing an XML version of it as defined by the W3C specification.






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






43. Allows us to invoke more than one servlet in sequence when the URL is opened with a common servlet alias.






44. Indicates that a variable or method can be used in subclasses from another package.






45. Evaluates interior code to a String and feeds it to the implicit "out" print writer (JspWriter) - done at time of JSP page request






46. 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.






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






48. A portable platform-independent reusable component model. A component that conforms to this model is called a bean.






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






50. A Java class that can be loaded into and run dynamically in a Servlet container on a web server; interact with web clients via a request-response model based on HTTP.
