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 set of APIs that support the integration of audio and video clips & 2D fonts & graphics and images as well as 3D models and telephony.






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






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






4. 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.






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






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






7. CRUD: Create - Retrieve - ________ - Delete






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






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






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






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






12. Creates an object from an existing class.






13. Includes a file in the page






14. Introduces a class






15. 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.






16. Creates a subclass






17. 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






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






19. 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.






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






21. 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.






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






23. 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.






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






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






26. An opensource Java Application Server






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






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






29. 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.






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






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






32. 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).






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






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






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






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






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






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






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






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






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






42. Reuses the functionality from a previously defined interface.






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






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






45. 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.






46. 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.






47. ______ uses HTML-like tags in a "*.jsp" web-page on a web server linked to from the client's web-browser as short-hand to render Java Servlet code in a Java .class file by the Servlet/JSP container (done by the "page-compiler" Servlet) running on the






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






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






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