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. A subset of the Java Development Kit (JDK) for end-users and developers who want to redistribute the runtime environment alone. The Java runtime environment consists of the Java virtual machine1 - the Java core classes and supporting files.






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






3. 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






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






5. 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.






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






7. Indicates that a value is a 32-bit whole number.






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






9. Forces the abrupt end of the current loop iteration and begins another iteration.






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

16. Introduces statements that are executed when something interrupts the flow of execution in a try clause.






17. A self-reference






18. 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.






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






20. Introduces a class






21. Similar to the include Directive but can pass information to the included resource






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






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






24. A principal native to the operating system on which the Java platform is executing.






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






26. 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






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






28. 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.






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






30. Creates a newly defined type






31. Jumps out of a loop or switch.

33. Introduces one of several possible paths of execution in a switch statement.

35. Puts the code into a package






36. In the Java programming language specification - describes a floating point number that holds 64 bits of data. See also single precision.






37. Keeps two threads from interfering with one another.






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






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






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






41. Refers to the superclass of the code in which the word super appears.






42. 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






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






44. Includes a file in the page






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

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






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






49. Basic code block of a JSP page






50. 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.
