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.

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

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






28. Keeps two threads from interfering with one another.






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






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

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

36. 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
