1. The Java language is:
a. Interpreted at run time.
b. Compiled to obtain executable target files.
c. Designed for recursive string processing.
d. Designed for matrix algorithm processing.

2. The Java language is designed to:
a. Run on a simulated Java machine.
b. Run directly on Intel microprocessors.
c. Designed for RISC computing architectures.
d. Designed for CISC computing architectures.

3. The Java language will run:
a. On any computer where the Java simulated machine is installed.
b. On any computer attached to the Internet.
c. On any computer with a Web browser installed.
d. On any computer which will also run C++.

4. The Java language provides the programmer with:
a. No ability to access or manipulate memory.
b. Protected access to machine memory.
c. Dynamically created data structures linked with pointers.
d. Access to the memory of a local machine through a network.

5. The Java language is:
a. An object oriented programming language.
b. A structured programming language.
c. A procedural programming language.
d. A stack oriented programming language.

6. The Java language was designed:
a. To create event driven programs with graphical interfaces.
b. To unify all different approaches to object orientation.
c. To provide a learning tool for beginning programmers.
d. To force programmers to implement all needed program elements themselves.

7. The Java language has most in common with the following language:
a. C#.                      b. C.                  c. C++.                 d. Basic.
8. The basis for object oriented programming can be found in which of the following?
a. All of the items listed.
b. It is an outgrowth of the availability of powerful hardware.
c. It is useful in the development of graphical user interfaces.
d. It solved some of the problems associated with structured programming.

9. That unit of code in Java that contains the specifications for objects is:
a. A class.          b. A method.         c. An instance variable.      d. A constructor.

10. Which of the following is true?
a. An object receives copies of all instance variables, but shares method code.
b. An object receives copies of all instance variables and all methods.
c. An object receives copies of all methods, but shares instance variables.
d. An object shares both instance variables and methods with other objects.

11. Encapsulation refers to the idea that:
a. Instance variables can only be accessed by means of methods.
b. Methods can only be accessed by means of instance variables.
c. All other methods must be defined within the main() method.
d. Instance variables can only be declared within methods.

12. In order to use objects of a given class the programmer needs to:
a. Know what the methods do, but not how they do it.
b. Know all of the instance variables of the class.
c. Know how the method algorithms were implemented.
d. Know the types of all of the instance variables of the class.

13. Java programs have to be saved with the following extension:
a. .java               b. .txt           c. .doc             d. .xls

14. In Java programs, the name of the class has to:
a. Be the same as the name of the file it is saved in.
b. Be different from the name of the file it is saved in.
c. Be all capital letters.
d. Be all small letters.
