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.
1. Used to generate HTML






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






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






4. Jumps out of a loop or switch.






5. 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.






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






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






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






9. CRUD: Create - Retrieve - ________ - Delete






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






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






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






13. ______ 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






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






15. 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.






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






17. Useful only for small sites






18. 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






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






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






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






22. Creates an object from an existing class.






23. Introduces a class






24. 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.






25. Reuses the functionality from a previously defined interface.






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






27. 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.






28. 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).






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






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






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






32. Basic code block of a JSP page






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






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






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






36. 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.






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






38. Keeps two threads from interfering with one another.






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






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






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






42. 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.






43. 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.






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






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






46. Includes a file in the page






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






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






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






50. 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()
