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






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






4. Creates a subclass






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






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






7. A distributed object model for Java program to Java program in which the methods of remote objects written in the Java programming language can be invoked from other Java virtual machines1 - possibly on different hosts.






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






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






10. ______ 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

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






13. 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.






14. 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()






15. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






30. 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.






31. 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.






32. 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






33. Jumps out of a loop or switch.






34. Basic code block of a JSP page






35. Includes a file in the page






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






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






38. 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.






39. Keeps two threads from interfering with one another.






40. Creates an object from an existing class.






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






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






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






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






46. An opensource Java Application Server






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






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