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






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






4. Jumps out of a loop or switch.






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






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






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






8. Creates a newly defined type






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






10. Imposes strict rules on the use of a variable by more than one thread at a time.






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






12. Refers to the superclass of the code in which the word super appears.






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






14. 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.






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






16. CRUD: Create - Retrieve - ________ - Delete






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






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






19. 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.






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






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






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






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






24. Indicates that a value is a 64-bit number with one or more digits after the decimal point.






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






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






27. 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.






28. Creates an object from an existing class.






29. 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






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






31. 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.






32. 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






33. 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.






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






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






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






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






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






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






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






41. Includes a file in the page






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






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






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






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






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






47. 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.






48. Introduces a class






49. 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






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
