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






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






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






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






5. 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






6. Used to generate HTML






7. Jumps out of a loop or switch.






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






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






10. 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.






11. 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.






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






13. 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.






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






15. Basic code block of a JSP page






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






17. Creates a newly defined type






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






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






20. This separates the content presentation (View) from the underlying business operations/content generation (Model) using infrastructure/controller Servlet (Controller) which exists between the client browser and the JSP/Servlet-generated pages. Contro






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






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






23. A tool for tracking and managing source file changes - written in Java.






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






25. A self-reference






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






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






28. Puts the code into a package






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






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






31. Keeps two threads from interfering with one another.






32. Introduces a class






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






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






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






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






37. 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.






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






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






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






41. Indicates that a value is a 32-bit number with one or more digits after the decimal point.






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






43. Tests to see whether a certain object comes from a certain class.






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






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






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






47. 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()






48. 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.






49. 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.






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