JAVA FOUNDATIONS 3rd Ed By JOHN LEWIS - TEST BANK

Chapter 1: Introduction

Multiple Choice Questions:

1)  _____________ consists of specific words and symbols to express a problem solution.

                        a) A programming language

                        b) Software

                        c) Hardware

                        d) A computer

                        e) An application

            Answer: a

            Explanation: A programming language consists of words and symbols to express a problem solution.  Software consists of programs and the data these programs use.   Hardware is the tangible parts of a computer, such as keyboards and hard disks.  A computer is made up of hardware and software, and an application is a program that runs on a computer.

2)  Java is _____________________.

                        a) a procedural language

                        b) a functional language

                        c) an object-oriented language

                        d) a fourth-generation language

                        e) a spoken-language

            Answer: c

            Explanation: Java is best described as an object-oriented language.  Procedural languages, functional languages and fourth-generation languages are different types of languages that don't necessarily include object-oriented features.  A spoken language is a language such as English or Spanish, and is too ambiguous for a computer to use.

3)  In Java, an identifier that is made up by the programmer can consist of ___________________.

                        a) any characters

                        b) only numbers

                        c) only letters

                        d) only letters, the underscore ( _ ), and the dollar sign ( $ )

                        e) numbers, letters, the underscore ( _ ), and the dollar sign ( $ )

            Answer: e

            Explanation: In Java, an identifier can consist of numbers, letters, the underscore and the dollar sign, but it cannot begin with a number.
4)  In order for a program to run on a computer, it must be expressed in ______________________.

                        a) an assembly language

                        b) a machine language

                        c) a high-level language

                        d) an object-oriented language

                        e) a fourth generation language

            Answer: b

            Explanation:  A computer can only understand its machine language.  Assembly languages, high-level languages, object-oriented languages and fourth generation languages are are languages that are easy for humans to understand, but they must first be translated into a machine language before they are run on a computer.

5)  A syntax error is a _____________________.

                        a) a logical error

                        b) a compile-time error

                        c) a run-time error

                        d) a bug

                        e) an exception

            Answer: b

            Explanation:  A program that contains a syntax error is invalid, and therefore cannot be compiled.  It is a compile-time error because it is caught by the compiler.  A logical error is an error that causes a running program to behave in an unexpected manner during run-time.  A bug is an example of a logical error.  A run-time error is an error that happens while the program is running.  In Java, run-time errors are called exceptions.

6)  Which of the following is not one of the four basic software development activities?

                        a) establishing the requirements

                        b) creating a design

                        c) preliminary practice coding

                        d) testing

                        e) implementing the design

            Answer: c

            Explanation:  Preliminary practice coding is not one of the four basic software development activities.  Establishing the requirements for a program, creating a design for a program, implementing the design and testing the program all occur during software development.
7)  Software requirements specify ____________________.
