Class
|
The blueprint for an object
|
|
|
|
Object
|
An instance of a class
|
|
|
|
Instance field
|
a class level variable
|
|
|
|
Constructor
|
a method that builds an object by setting initial data
|
|
|
|
Object Oriented Programming
|
a style of programming based on a series of interacting objects containing data and methods. this is in contrast to procedural programming. which uses no objects and progresses linearly through a set pattern
|
|
|
|
Scope
|
the visibility of a variable or method. this determines where you can access a given variable or method. so far we know that variables can be local, global, public
|
|
|
|
Public
|
An object's data or method that can be seen at any level of your program
|
|
|
|
Private
|
an object's data or method that can only be seen within that class
|
|
|
|
Literals
|
hard-coded numbers. Like "apple" or 42. they don't have names
|
|
|
|
Variables
|
store information and can change. they are named using camelCase
|
|
|
|
Constants
|
store information and never change. like final float PI = 3.14. Named with UPPERCASE_LETTERS
|
|
|
|
Finite State Automata (aka finite state machine)
|
an abstract machine that can be in one of a finite number of states. for example, Game of life has cells which are in the "alive" or "dead" states.
|
|
|
|
Generic Class (aka Template Class)
|
a class that can represent many different types
|
an ArrayList can be an ArrayList<String> or and ArrayList<Integer>
|
|
|
Definite Loop
|
a loop where you know the exact number of iterations prior to entering the loop.
|
a for loop
|
|
|
Indefinite loop
|
Anloop that waits for some condiyion to become true. in general, it's not obvious how many interactions it takes.
|
a while loop
|
|
|
Infinite Loop
|
a loop that does not terminate
|
|
|
|
Iteration
|
the repetition of a process, or, put simply "one pass through a loop"
|
|
|
|
Data structure
|
a way to organize data. examples include arrays, lists,stacks and queues
|
|
|
|
Array
|
a group of objects with the same attributes that can be addressed individually.
rows=horizontal, cols=vertical rows come before cols ex minefield[r][c] |
|
|
|
Code
|
instructions written by a programmer in a programming language
|
|
|
|
Hardcoding
|
programming code that solve a probnlem , but offers little flexibility to future modifications. sloppy and often resuiltss in more work
|
|
|
|
camelCase
|
a naming convention for writing code. each variable or method starts with a lowercase letter then capitalizes each subsequent word
|
|
|
|
Conditional
|
a part of your code that changes based on conditions. this is commonly implemented using if, else if, and else statements
|
|
|
|

|
|
|
|
assignment
|
setting a variable equal to a new value
|
|
|
|
initialization
|
when you declare a variable and assign it an initial value
|
|
|
|
Global variable
|
a variable declared outside of any methods. can be used everywhere
|
|
|
|
Local variable
|
a variable declared inside a method that only can be used in that method
|
|
|
|
