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






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






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






4. Basic code block of a JSP page






5. Creates a newly defined type






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






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






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






9. 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.






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






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






13. Indicates that a variable or method can be used in subclasses from another package.






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






15. 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).






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






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






18. 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.






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






20. Creates an object from an existing class.






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






22. 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






23. Includes a file in the page






24. 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.






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






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






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






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






29. 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






30. 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.






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






32. Run-once code blocks which run once at beginning of page load for initialization tasks - can appear anywhere in .jsp page itself - useful for overload JspInit() and JspDestroy()






33. 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.






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






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






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






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






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






39. 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.






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






41. Puts the code into a package






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






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






44. 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.






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






46. In the Java programming language specification - describes a floating point number that holds 64 bits of data. See also single precision.






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






48. Useful only for small sites






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






50. A special Java servlet-aware web server process.
