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 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.






2. Introduces a class






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






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






5. 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.






6. 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.






7. Useful only for small sites






8. 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.






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






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






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






12. Reuses the functionality from a previously defined interface.






13. Used to generate HTML






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






15. 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).






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






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






18. Includes a file in the page






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






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






21. 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.






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






23. Puts the code into a package






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






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






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






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






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






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






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






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






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






33. 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






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






35. Keeps two threads from interfering with one another.






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






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






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






39. 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.






40. CRUD: Create - Retrieve - ________ - Delete






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






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






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






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






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






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






47. 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()






48. Creates an object from an existing class.






49. Jumps out of a loop or switch.






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