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.

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






5. Useful only for small sites

7. CRUD: Create - Retrieve - ________ - Delete






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

12. ______ 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






13. 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.






14. Keeps two threads from interfering with one another.






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

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

24. 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






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