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. 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.






2. A self-reference






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






4. Creates a newly defined type






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






6. 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.






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






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






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






10. 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.






11. Indicates that a value is a 32-bit number with one or more digits after the decimal point.






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






13. 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.






14. 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






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






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






17. 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






18. 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.






19. Includes a file in the page






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






21. Useful only for small sites






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






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






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






25. Creates an object from an existing class.






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. 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.






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






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






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






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






32. 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()






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






34. 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






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






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






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






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






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






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






41. Basic code block of a JSP page






42. ______ 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






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






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






45. 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.






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






47. Puts the code into a package






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






49. 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.






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