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 -oriente d languages are run by declaring and using objects that contain data and methods .

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 term s 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; th ey 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 Solution and Answer Guide : Farrell, Java Programming 10e, [ 978-035-767-3423 ], Chapter 1: Creating Java Programs 3 © 2022 Cengage.

Variables are named memory locations , and c onstants 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.

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
