Chapter 1 Introduction to Computers and Java

While __________ is centered on creating procedures, __________ is centered on creating objects.

• procedural programming, object-oriented programming

• object-oriented programming, procedural programming

• routine programming, method programming

• procedural programming, class programming

Which of the following commands will run the compiled Java program named DoItNow?

• run DoItNow

• java DoItNow.java

• java DoItNow

• go DoItNow

RAM is usually

• an input/output device

• a volatile type of memory, used for temporary storage

• secondary storage

• a static type of memory, used for permanent storage

The two primary methods of programming in use today are

• procedural and object-oriented

• hardware and software

• practical and theoretical

• desktop and mobile

Validating the results of a program is important to

• correct runtime errors

• make sure the program solves the original problem

• create a model of the program

• correct syntax error

Software refers to

• programs

• the physical components a computer is made of

• firmware

• data stored in RAM

Assume you are at the operating system command line and want to use the following command to compile a program:

javac MyClass.java

Before entering the command you must

• close all open windows on your computer system

• make sure you are in the same directory or folder where the MyClass.java file is located

• execute the java.sun.com program

• save the program with the .comp extension

An object typically hides its data but allows outside code access to

• the pseudocode

• the methods that operate on the data

• private data members

• the data files

Variables are

• symbolic names made up by the programmer and once created, their values cannot be changed

• operators that perform operations on one or more operands

• symbolic names made up by the programmer that represent memory locations

• reserved words

__________ refers to the physical components that a computer is made of.

• Input

• Main Memory

• Motherboard

• Hardware
