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






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






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






4. 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






5. 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






6. Creates a newly defined type






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






8. Reuses the functionality from a previously defined interface.






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






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






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






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






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






14. CRUD: Create - Retrieve - ________ - Delete






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






16. 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.






17. 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.






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






19. A self-reference






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






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. Keeps two threads from interfering with one another.






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






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






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






26. An opensource Java Application Server






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






28. Puts the code into a package






29. Jumps out of a loop or switch.






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






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






32. 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.






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






34. This separates the content presentation (View) from the underlying business operations/content generation (Model) using infrastructure/controller Servlet (Controller) which exists between the client browser and the JSP/Servlet-generated pages. Contro






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






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






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






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






39. Indicates that a variable or method can be used in subclasses from another package.






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






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






42. 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.






43. 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.






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

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






49. 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).






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