mutator method
controls changes to variables
implicit parameter
reference object method is being called on
object
an instance of a class; properties defined by what that class is
cast
to reassign the class of an object
instruction set
all operations that can be executed by a processor
bit
unit of info in system; either 0 or 1
memory
unit of computer that stores instructions/data
megabyte
20^20 bytes; 1,000,000 bytes
encapsulation
hiding of implementation details; combine private variables with methods to set and/or get their values
byte
8-bits used to encode single character
Memory Data Register (MDR)
stores value to be fetched/stored
initialize
call to constructor OR assigning value to a variable
parameter
define what is going to be input into method
parameter passing
specifying expressions to be arguments for a method when called
address
unique identifier for a cell in RAM
accessor method
accesses value of object (getter)
loop
repeats action while a given command is true
machine language
programming language consisting of binary or hex instructions a computer can respond to
instance variable
variables within class (outside of methods) that apply to all methods
IDE
provides programmers with code editor, debugger, etc.
class
the blueprints of an object; an object of a specific class (declared, instantiation, initialization)
instantiation
creation of a class (object)
gigabyte
2^30 bytes; 1,000,000,000 bytes
I/O buffer
memory as part of I/O controller; stores data during transfer to output/input
boolean operator
used to alter boolean value in expression; and, or, not
boolean
datatype that's either true or false
object-oriented programming
programming focused on creation of objects over doing actions
kilobyte
2^10 bytes; 1024 bytes
primitive data type
most basic data types in Java; boolean, byte, char, short, int, long, float, double
mass storage
large amounts of permanent storage (USB, disc, etc.)1
I/O controller
special computer that handles details of input output
arithmetic/logic unit
carries out arithmetic/logic operations for computer
Memory Address Register (MAR)
stores address of cell to access
binary
numerical notation in base-2
object reference
points to the location of an object
logic gate
building block of digital circuits; takes 2 binary inputs and returns binary output
instance
creation of a new class (object)
cache memory
small space to hold data + neighbors from RAM and access faster
algorithm
A methodical, logical rule or procedure that guarantees solving a particular problem.
computer science
studying the principles of computers and their use
constructor
method used to create a new object
boolean expression
logical expression that evaluates true or false
formal parameter
parameters of method - establishes datatype of input and name of input
explicit parameter
arguments of a method when called
method
set of code which can be called by using the method's name
argument
actual parameter; entered into method when calling it
control unit
directs operations of processor; guides ALU and output devices
local variable
variables only apply to the methods that contain them
actual parameter
argument; values entered when calling method
ASCII
8-bit encoding of characters; 256 options (32-126 are printable)
