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






2. 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.






3. Puts the code into a package






4. 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






5. 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.






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






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






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






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






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. Jumps out of a loop or switch.






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






13. 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






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






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






16. A self-reference






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






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






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






20. 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).






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






22. Keeps two threads from interfering with one another.






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

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






26. 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






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






28. 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.






29. A tree of objects with interfaces for traversing the tree and writing an XML version of it as defined by the W3C specification.






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






31. Reuses the functionality from a previously defined interface.






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






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






34. 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.






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






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






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






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






39. 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.






40. 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.






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






42. Creates an object from an existing class.






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