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. Creates a subclass






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






3. 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.






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






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






6. Used to generate HTML






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






8. Includes a file in the page






9. Jumps out of a loop or switch.






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






11. An opensource Java Application Server






12. 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






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






14. ______ 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






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






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






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






18. 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()






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






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






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






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






23. A self-reference






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






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






26. 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.






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






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






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






30. 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.






31. 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.






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






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






34. 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.






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






36. 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.






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






38. 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).






39. Keeps two threads from interfering with one another.






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






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






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






43. Basic code block of a JSP page






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






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






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






47. 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.






48. 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.






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






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