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. An opensource Java Application Server






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






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






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






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






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






7. Useful only for small sites






8. The output of one servlet act as a input to another servlet.






9. 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






10. 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).






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






12. 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.






13. 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






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






15. 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.






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






17. 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.






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






19. Includes a file in the page






20. Jumps out of a loop or switch.






21. A standard programming interface for writing Java native methods and embedding the JVM into native applications. The primary goal is binary compatibility of native method libraries across all JVM implementations on a given platform.






22. Creates a newly defined type






23. 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.






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






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






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






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






28. 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.






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






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






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






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






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






34. Indicates that a value is a 16-bit whole number.






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






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






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






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






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






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






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






44. 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.






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






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






47. Creates a subclass






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






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






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