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. 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.






2. ______ 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






3. Basic code block of a JSP page






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






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






6. 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.






7. 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






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






9. 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.






10. Refers to the superclass of the code in which the word super appears.






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






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. Jumps out of a loop or switch.






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






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






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






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






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






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






20. 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.






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






22. 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.






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






24. Introduces a class






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






26. Indicates that a method or constructor may pass the buck when an exception is thrown.






27. Sets attributes and properties specific to the current JSP page






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






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






30. A self-reference






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






32. Creates a subclass






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






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






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






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






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






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






39. Forces the abrupt end of the current loop iteration and begins another iteration.






40. Useful only for small sites






41. A software "execution engine" that safely and compatibly executes the byte codes in Java class files on a microprocessor (whether in a computer or in another electronic device).






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






43. Introduces one of several possible paths of execution in a switch statement.






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






45. Two Servlet API packages: javax.servlet.* ___________






46. 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.






47. Used to generate HTML






48. _______ separates Java code/functionality from page design and use of tags in JSP and allows for re-use of beans






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






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