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






2. An opensource Java Application Server






3. Tells the computer to follow one of many possible paths of execution (one of many possible cases) depending on the value of an expression.






4. Introduces a class






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






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






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






8. 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.






9. Creates a newly defined type






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






11. Creates an object from an existing class.






12. 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).






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






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






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






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






17. 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.






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






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






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






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






22. 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.






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






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






25. 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.






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






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






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






29. Reuses the functionality from a previously defined interface.






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






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






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






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






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






35. Used to generate HTML






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






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






38. Useful only for small sites






39. A self-reference






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






41. CRUD: Create - Retrieve - ________ - Delete






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






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






44. 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






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






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






47. 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






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






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






50. 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).
