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 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.






2. Creates a newly defined type






3. Puts the code into a package






4. 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.






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






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






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






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






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






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






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






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






13. Indicates that a value is a character (a single letter or digit or punctuation symbol and so on) stored in 16 bits of memory.






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






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






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






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






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






20. ______ 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






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






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






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






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






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






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






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






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






29. 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.






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






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






32. 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.






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






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






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






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






37. An opensource Java Application Server






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






39. Introduces statements that are watched (during runtime) for things that can go wrong.






40. Basic code block of a JSP page






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






42. 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.






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






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






45. Jumps out of a loop or switch.






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






47. 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).






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






49. 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






50. 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.
