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. Reuses the functionality from a previously defined interface.






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






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






4. 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.






5. Includes a file in the page






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






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






8. 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.






9. An opensource Java Application Server






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






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






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






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. 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






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






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






17. 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






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






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






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






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






22. 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.






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






24. 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






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






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






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






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






29. Creates a newly defined type






30. 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.






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






32. 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.






33. Indicates that the details of a class or a method or an interface are given elsewhere in the code.






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






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






36. Useful only for small sites






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






38. 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.






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






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






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






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






43. 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.






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






45. Creates a subclass






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






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






48. Puts the code into a package






49. 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).






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