Intro. to Java Programming UPDATED ACTUAL Exam Questions
and CORRECT Answers
Cable Modem - Uses the cable TV line maintained by the cable company and is generally faster
than DSL
Central Processing Unit (CPU) - The part of a computer (a microprocessor chip) that does most
of the data processing. 2 parts; Control Unit and Arithmetic/LogicUnit.
Class Loader - Is a part of the Java Runtime Environment that dynamically loads Java classes
into the Java Virtual Machine. Usually classes are only loaded on demand. The Java run time
system does not need to know about files and file systems because of class loaders.
Comment - Help programmers to communicate and understand the program. (//) single line
comment. (/**/) multiply line comment
Compiler - Is a computer program (or set of programs) that transforms source code written in a
programming language into another computer language (the target language, often having a
binary form known as object code). The most common reason for wanting to transform source
code is to create an executable program.
Console - Is an old computer term that refers to the text entry and display device of the computer.
Dot Pitch - The amount of space between pixels, measured in millimeters. The smaller the dot
pitch the sharper the display.
Digital Subscriber Line (DSL) - Is a family of technologies that provide Internet access by
transmitting digital data over the wires of a local telephone network.
Encoding Scheme - Is a set of rules that govern how a computer translates characters, numbers,
and symbols into data the computer can actually work with.
,Hardware - In general hardware comprises the visible physical elements of the computer.
High-Level Language - Is a programming language with strong abstraction from the details of
the computer. In comparison to low-level programming languages, it may use natural language
elements, be easier to use, or may automate (or even hide entirely) significant areas of computing
systems (e.g. memory management), making the process of developing a program simpler and
more understandable relative to a lower-level language.
Integrated Development Environment (IDE) - Is a software application that provides
comprehensive facilities to computer programmers for software development. An IDE normally
consists of a source code editor, build automation tools and a debugger.
Interpreter - Changes the source code into machine code for execution.
Java Command - ...
Java Language Specification - Is a technical definition of the Java programming language's
syntax and semantics.
Java Virtual Machine (JVM) - Iis a virtual machine that can execute Java bytecode. It is the code
execution component of the Java platform.
Javac Command - ...
Keyword (or reserved word) - Have specific meaning to the compiler and cannot be used for
other purposes in the program.
Library - Contains predefined classes and interfaces for developing Java programs.
, Line Comment - // is used by programmers to relay information about coding in the program.
Java Development Toolkit (JDK) - The software for developing and running Java programs.
Array - a collection of a fixed number of components wherein all of the components have the
same data type
How the components arranged in a one-dimensional array? - In a list form
index - any expression whose value is a nonnegative integer
The array index always starts at... - 0
Base address - the address, or memory location, of the first array component
T or F:
A Method can return a value of the type array - True
T or F:
A Method CANNOT return a value of the type array - False
T or F:
The base address of an array is the address of the first array component - True
Algorithm - A step-by-step procedure for calculations. Algorithms are used for calculation, data
processing, and automated reasoning.
