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. 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.






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






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






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






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






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






7. 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.






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






9. Indicates that a method doesn't return a value.






10. Indicates that a value is either true or false in the Java sense.






11. Creates an object from an existing class.






12. 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






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






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






15. CRUD: Create - Retrieve - ________ - Delete






16. Indicates that a variable or method belongs to a class rather than to any object created from the class.






17. A class that wraps primitives - Integer or Boolean...






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






19. Tests to see whether a condition is true. If it's true the computer executes certain statements; otherwise the computer executes other statements.






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






21. 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 goto variable.






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






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






24. A self-reference






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






26. 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).






27. Reuses the functionality from a previously defined interface.






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






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






30. Used to terminate the execution of the current JSP page and switch control to another resource






31. An opensource Java Application Server






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






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






34. Puts the code into a package






35. 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.






36. 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






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






38. Introduces statements that are executed when the condition in an if statement isn't true.






39. Useful only for small sites






40. 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






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






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






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






44. ______ 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

50. Creates a newly defined type
