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.

2. An opensource Java Application Server






3. Includes a file in the page






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

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






12. 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()






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






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






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






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






17. Introduces the last will and testament of the statements in a try clause.






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






19. Reuses the functionality from a previously defined interface.






20. Introduces a class






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






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






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






30. Tells the computer to follow one of many possible paths of execution (one of many possible cases) depending on the value of an expression.






31. A self-reference






32. 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.






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






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






35. 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






36. 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.






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






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






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






40. A lock that can be counted - i.e. how many times a resouce has been accessed and locked






41. 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.






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






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






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

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






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






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






49. 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.






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