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






2. 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.






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






4. Indicates that a value is a 32-bit whole number.






5. 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.






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






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






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






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






10. 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.






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






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






13. 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.






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






15. A self-reference






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






17. Useful only for small sites






18. ______ 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






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






20. A description of the structure and properties of a class of XML files.






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






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






23. 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.






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






25. 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






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






27. 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()






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






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






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






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






33. Basic code block of a JSP page






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






35. Puts the code into a package






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






37. Creates an object from an existing class.






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






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






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






41. 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.






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






43. 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






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






45. Jumps out of a loop or switch.






46. 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.






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






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






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






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