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.

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






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

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






35. Reuses the functionality from a previously defined interface.






36. Keeps two threads from interfering with one another.






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






38. 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






39. 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.

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






48. An opensource Java Application Server






49. 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.
