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






2. Useful only for small sites






3. 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.






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






5. 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.






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






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






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






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






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






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






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






13. 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.






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






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






16. 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.






17. Creates a subclass






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






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






20. CRUD: Create - Retrieve - ________ - Delete






21. 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






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






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






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






25. Creates an object from an existing class.






26. Puts the code into a package






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






28. 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).






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






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






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






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






33. 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.






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






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






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






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






38. 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






39. 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.






40. Used to generate HTML






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






42. Indicates that a value is a 64-bit whole number.






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

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






46. Keeps two threads from interfering with one another.






47. 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.






48. 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






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






50. ______ 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
