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






3. CRUD: Create - Retrieve - ________ - Delete






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






5. Introduces a class






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






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






8. An opensource Java Application Server






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






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






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






12. 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






13. Basic code block of a JSP page






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






15. ______ 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






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






17. 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.






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






19. Used to generate HTML






20. A self-reference






21. A lock that can be counted - i.e. how many times a resouce has been accessed and locked






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






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






24. Keeps two threads from interfering with one another.






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






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






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






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






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






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






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






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






33. 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






34. 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.






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






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






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






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






39. 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.






40. 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.






41. 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.






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






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






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






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






46. 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.






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






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






49. 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.






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