Review Questions Answers
1. The most basic circuitry-level computer language is ____________.
a. machine language
b. Java
c. high-level language
d. C++
Answer: a
Feedback:
The most basic circuitry-level computer language is machine language. Machine language, or
machine code, is the most basic set of instructions a computer can execute. Java and C++ are
both high-level languages and are the opposite of circuitry-level computer language.
2. Languages that let you use an easily understood vocabulary of descriptive terms, such as read, write,
or add, are known as ____________languages.
a. procedural
b. high-level
c. machine
d. object-oriented
Answer: b
Feedback:
High-level languages use English-like terms; Java is an example of a high-level language.
Procedural languages are those that run by executing a series of procedures or methods.
Machine-level languages do not use English-like terms; they use 1s and 0s. Object-oriented
languages are run by declaring and using objects that contain data and methods.

3. The rules of a programming language constitute its ____________.
a. syntax
b. logic
c. format
d. objects
Answer: a
Feedback:
The rules of a programming language constitute its syntax.
4. A ____________ translates high-level language statements into machine code.
a. programmer
b. syntax detector
c. compiler
d. decipherer
Answer: c
Feedback:
A compiler translates high-level language statements into machine code. A programmer
writes high-level language statements but does not translate them. “Syntax detector” and
“decipherer” are not terms used in programming.
5. Named computer memory locations are called ____________.
a. compilers
b. variables
c. addresses
d. appellations
Answer: b
Feedback:
Named computer memory locations are variables. Compilers translate programming
statements into machine language; they are not memory locations. Addresses are unnamed
computer memory locations. “Appellations” is not a term used in programming.
6. The individual operations used in a computer program are often grouped into logical units called
____________.
a. procedures
b. variables

c. constants
d. logistics
Answer: a
Feedback:
The individual operations used in a computer program are often grouped into logical units
called procedures. Variables are named memory locations, and constants are values that do
not change; they are not groups of logical operations. “Logistics” is not a term commonly used
in programming.
7. Envisioning program components as objects that are similar to concrete objects in the real world is
the hallmark of ____________.
a. command-line operating systems
b. procedural programming
c. object-oriented programming
d. machine languages
Answer: c
Feedback:
Envisioning program components as objects that are similar to concrete objects in the real
world is the hallmark of object-oriented programming.
8. The values of an object’s attributes are known as its ____________.
a. state
b. orientation
c. methods
d. condition
Answer: a
Feedback:
The values of an object’s attributes are known as its state.
9. An instance of a class is a(n) ____________.
a. method
b. procedure
c. object
d. case
Answer: c

10. Java is architecturally ____________.
a. neutral
b. oriented
c. specific
d. abstract
Answer: a
Feedback:
Java is architecturally neutral.
11. You must compile classes written in Java into ____________.
a. bytecode
b. source code
c. Javadoc statements
d. object code
Answer: a
Feedback:
You must compile classes written in Java into bytecode. Source code is the high-level
programming statements. Javadoc statements are a type of comment used for
documentation. Object code is the low-level code produced when a compiler translates high-
level code.
12. All Java programming statements must end with a ____________.
a. period
b. comma
c. closing parenthesis
d. semicolon
Answer: d
Feedback:
All Java programming statements must end with a semicolon.
13. Arguments to methods always appear within ____________.
a. parentheses
