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






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






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






4. Introduces a class






5. Creates a subclass






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






7. CRUD: Create - Retrieve - ________ - Delete






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






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






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






11. 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.






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






13. 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.






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






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






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






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






18. 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






19. Basic code block of a JSP page






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. A software development environment for writing applets and application in Java .






22. An opensource Java Application Server






23. 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.






24. 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).






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






26. 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.






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






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






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






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






31. Keeps two threads from interfering with one another.






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






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






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






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






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






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






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






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






41. Puts the code into a package






42. 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






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






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






45. Tests to see whether a condition is true. If it's true the computer executes certain statements; otherwise the computer executes other statements.






46. 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.






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






48. Creates a newly defined type






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






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