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. Includes a file in the page






3. Indicates that the details of a class or a method or an interface are given elsewhere in the code.






4. 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).






5. 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.






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






7. Repeats some statements over and over again (as long as a condition is still true).






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






9. 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






10. 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.






11. 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.






12. 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.






13. Indicates that a variable or method can be used in subclasses from another package.






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






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






16. Introduces statements that are executed when something interrupts the flow of execution in a try clause.






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






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






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






20. 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.






21. 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






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






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






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






25. Tests the truth of a condition that the programmer believes is true.






26. 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()






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






28. 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






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






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






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






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






33. 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






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






35. An opensource Java Application Server






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






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






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






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






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






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






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






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






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






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






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






47. A self-reference






48. 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.






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






50. 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.
