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






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






3. Creates a subclass






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






5. 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.






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






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






8. 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.






9. 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.






10. 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






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






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






13. 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.






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






15. 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.






16. 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).






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






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






19. 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.






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






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






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






23. 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.






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






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






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






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






28. 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.






29. 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.






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






31. 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).






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






33. 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.






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






36. Includes a file in the page






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






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






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






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






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






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






43. Useful only for small sites






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






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






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






47. ______ 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






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






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






50. 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.
