Java Programming Basics

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.

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






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






6. A self-reference






7. Indicates that a value is a 64-bit number with one or more digits after the decimal point.

12. Repeats some statements over and over again (as long as a condition is still true).






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






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






15. 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






16. 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.






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






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






19. Includes a file in the page






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






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






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






23. Consists of class libraries - a Java virtual machine (JVM) and class loader (which comprise the runtime environment) and a compiler - debugger and other tools (which comprise the development kit).






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






25. 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()






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






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






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






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






30. 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






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






32. The core framework supports clocks for synchronizing between different media (e.g. audio and video output). The standard extension framework allows users to do full audio and video streaming.






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






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






35. Creates a newly defined type

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






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

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






45. An opensource Java Application Server






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






47. 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.






48. Puts the code into a package






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






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