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






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






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






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






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






6. Introduces a class






7. 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.






8. Consists of class libraries - a Java virtual machine (JVM) and class loader (which comprise the runtime environment) and a compiler - debugger and other tools (which comprise the development kit).






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






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






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






12. Includes a file in the page






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






14. Type of Java program (as opposed to a stand-alone program) which is embedded in a web page (requested from a server) and run on a client-side browser






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






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






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






18. 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.






19. Creates a subclass






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






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






22. 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.






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






24. 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.






25. 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.






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






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






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






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






30. Puts the code into a package






31. Indicates that a value is a 64-bit number with one or more digits after the decimal point.






32. An opensource Java Application Server






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






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






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






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






37. Useful only for small sites






38. 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).






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






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






41. ______ 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






42. 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.






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






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






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






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






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






48. Tests to see whether a certain object comes from a certain class.






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






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