TEST BANK FOR Java Programming 10th Edition Solution By Farrell (VERIFIED) Solution and Answer Guide. 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. 2 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 3 ____________. 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) ____________. 4 a. method b. procedure c. object d. case Answer: c Feedback: An instance of a class is an object. 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 highlevel code. 12. All Java programming statements must end with a ____________. a. period b. comma c. closing parenthesis EMAIL ME: EMAIL ME: Solution and Answer Guide: Farrell, Java Programming 10e, [978-035-767-3423], Chapter 1: Creating Java Programs 5 d. semicolon Answer: d Feedback: All Java programming statements must end with a semicolon. 13. Arguments to methods always appear within ____________. a. parentheses b. double quotation marks c. single quotation marks d. curly braces Answer: a Feedback: Arguments to methods always appear within parentheses. 14. In a Java program, you must use ____________ to separate classes, objects, and methods. a. commas b. semicolons c. dots d. forward slashes Answer: c Feedback: In a Java program, you must use dots to separate classes, objects, and methods. 15. All Java applications must have a method named ____________. a. method() b. main() c. java() d. Hello() Answer: b Feedback: All Java applications must have a method named main(). Although an application could have a method named method(), java(), or Hello(), they are not required method EMAIL ME: 6 names. Hello()also is not a conventional name because methods usually start with a lowercase letter. 16. Nonexecuting program statements that provide documentation are called ____________. a. classes b. notes c. comments d. commands Answer: c Feedback: Nonexecuting program statements that provide documentation are called comments. 17. Java supports three types of comments: ____________, ____________, and Javadoc. a. line, block b. string, literal c. constant, variable d. single, multiple Answer: a Feedback: Java supports line, block, and Javadoc comments. 18. Which of the following is not necessary to do before you can run a Java program? a. coding b. compiling c. saving d. debugging Answer: d Feedback: Although you should debug a program, it can run with bugs—it simply will produce incorrect results. You must code, compile, and save a program before you can run it. 19. The command to execute a compiled Java application is ____________. a. run EMAIL ME: EMAIL ME: 7 b. execute c. javac d. java Answer: d Feedback: The command to execute a compiled Java application is java. The command to compile a program is javac. 20. You save text files containing Java source code using the file extension ____________. a. .java b. .class c. .txt d. .src Answer: a Feedback: You save text files containing Java source code using the file extension .java. Programming Exercises Solutions 1. Is each of the following class identifiers (a) legal and conventional, (b) legal but unconventional, or (c) illegal? a. myClass b. void c. Golden Retriever
