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






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






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






4. 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.






5. 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.






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






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






8. CRUD: Create - Retrieve - ________ - Delete






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






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






11. 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.






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






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






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






15. 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.






16. Two Servlet API packages: javax.servlet.* ___________






17. Creates a newly defined type






18. 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).






19. 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






20. Indicates that a variable or method can be used only within a certain class.






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






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






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






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






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






26. Puts the code into a package






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






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






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






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






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






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






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






35. Keeps two threads from interfering with one another.






36. 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.






37. Creates an object from an existing class.






38. 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.






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






40. A self-reference






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






42. 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.






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






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






45. 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






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






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






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






49. 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






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