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. ______ uses HTML-like tags in a "*.jsp" web-page on a web server linked to from the client's web-browser as short-hand to render Java Servlet code in a Java .class file by the Servlet/JSP container (done by the "page-compiler" Servlet) running on the






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






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






4. Creates a subclass






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






6. Common Object Request Broker Architecture. A language independent distributed object model specified by the Object Management Group (OMG).






7. Introduces a class






8. 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.






9. 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.






10. Includes a file in the page






11. Tests the truth of a condition that the programmer believes is true.






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






13. An opensource Java Application Server






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






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






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






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






18. Keeps two threads from interfering with one another.






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






20. Indicates that a variable's value cannot be changed - that a class's functionality cannot be extended or that a method cannot be overridden.






21. A software development environment for writing applets and applications in the Java programming language. Technically - the JDK is the correct name for all versions of the Java platform from 1.0 to 1.1.x.






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






23. Run-once code blocks which run once at beginning of page load for initialization tasks - can appear anywhere in .jsp page itself - useful for overload JspInit() and JspDestroy()






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






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






26. A set of Java APIs that provide CORBA (Common Object Request Broker Architecture) interoperability and connectivity capabilities for the J2EE platform. These capabilities enable J2EE applications to invoke operations on remote network services using






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






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






29. 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






30. Puts the code into a package






31. Creates an object from an existing class.






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






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






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






35. 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.






36. Creates a newly defined type






37. Indicates that a value is an 8-bit whole number.






38. A self-reference






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






40. Basic code block of a JSP page






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






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






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






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






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






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






47. Jumps out of a loop or switch.






48. Indicates that a value is a character (a single letter or digit or punctuation symbol and so on) stored in 16 bits of memory.






49. Reuses the functionality from a previously defined interface.






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