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






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






3. 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






4. 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.






5. 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.






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






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






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






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






10. 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






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






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






14. 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).






15. Creates an object from an existing class.






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






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






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






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






20. 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.






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






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






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






24. 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.






25. Basic code block of a JSP page






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






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






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






29. Servlet is: loaded by servlet container when 1st requested; is then forwarded the user's request; processes the user's request; returns the response back to the servlet container. Servlet container sends this response back to the user. Servlet stays






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






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






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






33. A self-reference






34. Common Object Request Broker Architecture. A language independent distributed object model specified by the Object Management Group (OMG).






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






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






37. 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.






38. Includes a file in the page






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






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






41. Creates a newly defined type
