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






2. 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()






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






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






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






6. 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.






7. Creates a subclass






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






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






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






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






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






13. 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.






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






15. 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.






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






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






18. 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.






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






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






21. 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.






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






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






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






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






26. A self-reference






27. 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






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






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






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






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






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






33. Used to generate HTML






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






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






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






37. Introduces a class






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






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






40. 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).






41. An opensource Java Application Server






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






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






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






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






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






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






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






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






50. 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
