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






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






3. Used to generate HTML






4. ______ 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






5. Keeps two threads from interfering with one another.






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






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






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






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






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






11. 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






12. 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.






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






14. This separates the content presentation (View) from the underlying business operations/content generation (Model) using infrastructure/controller Servlet (Controller) which exists between the client browser and the JSP/Servlet-generated pages. Contro






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






16. A technology that provides distributed persistence and data exchange mechanisms for code in Java.






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






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






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






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






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






22. 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.






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

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






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