TEST BANK FOR Java Programming 10th Edition Solution By Farrell 2024/2025 (Solution and Answer Guide) 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. 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.

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.
