Data hiding

(ans) refers to an object's ability to hide its data from code that is outside that object

Encapsulation

Class

A (ans) is the blueprint of the object that is created from it

instance

Another term for an object of a class is

nouns

The starting point for finding the needed classes for a project is to identify all of the __________ in the problem statement / requirements.

-Declares array1 to be a reference to an array of double values -Creates an instance of an array of 10 double values -Will allow valid subscripts in the range of 0 - 9

What does the following statement do? double[] array1 = new double[10];

An error will occur at runtime.

What will be the results of the following code? final int ARRAY_SIZE = 5; double[] x = double[ARRAY_SIZE]; for(int i = 1; i <= ARRAY_SIZE; i++) { x[i] = 10.0; }

38

What will be the value of x[1] after the following code is executed? int[] x = {22, 33, 44}; arrayProcess(x); ... public static void arrayProcess(int[] a) { for(int k = 0; k < 3; k++) { a[k] = a[k] + 5; } }

33

What will be the value of x[1] after the following code is executed? int[] x = {22, 33, 44}; arrayProcess(x[1]); ... public static void arrayProcess(int a) { a = a + 5; }

sorting

a (ans) algorithm is a technique for stepping through an array and rearranged its contents in some order

text

a (ans) file contains data that has been encoded as text, using one of the computer's encoding schemes

class

a (ans) is a code that specified the fields and methods for a particular type of object

constructor

a (ans) is a method that automatically called when an object is created

Object names

a UML diagram does not contain (ans)

data type

all the values in an array must be of the same (ans)

array

an (ans) allows you to store a group of items of the same data type together in memory

object

an (ans) is not a stand-alone program, but is used by programs that need its service

list

arrays are designed to store and process a (ans) of data

subscript

by using the same (ans) a relationship can be established with the data stored between two or more arrays

records

data in a file is organized in (ans), which are a complete set of data about in an item

instance

each object that is created from a class is called an (ans) of the class

n/2

for an array of n items, the average number of comparisons in a sequential search (ans)

n

for an array of n items, the maximum number of comparisons in a sequential search is (ans)

control is returned to method c

if method A calls method B, and method B calls method C, and method C calls method D, when method D finishes, what happens

10

if the subscripts of an array go from 0 through 9, then the size of the array is (ans)

descending

if the values in an array are sorted in (ans) order, then they are stored from highest to lowest

ascending

if the values in an array are sorted in (ans) order, they are sorted from lowest to highest

0

in a selection sort, the first step is to move the smallest value in the array to element (ans) in order to sort the array in ascending order

relational

in a sorting algorithm, the sort order can be changes by changing the (ans) operator

parallelogram

in flowcharting, the (ans) symbol is used to read data from a file

erased

in most languages, if a file with the specified external name already exists when the file is opened, the contents of the existing file will be (ans)

nonnegative

in most programming languages, an array size declaratory must be a (ans) integer

bubble

in the bubble sort algorithm, the movement of the sorted values is commonly described as seeming to (ans) toward the end/beginning of the array

accumulator

loops are used to total the values in a numeric array, by which process the loop steps through the array adding the value of each array element to the (ans)

class

one or more objects may be created from an (ans)

two

passing an array as an argument requires that you pass (ans) arguments

bounds

programming languages perform array (ans) checking, which mean they do not allow a program to use an invalid array subscript

this is a public method with a parameter of data type double and does not return a value

what does the following UML diagram entry mean? +setHeight(h: double) : void

closes

when a program (ans) a file, it disconnects the file from the program

file

when a program needs to save data for later use, it writes the data to a (ans)

reading

when a program performs the task of retrieving data from a file, it is known as (ans) data from/to the file

selection

when placing the elements in an array in descending order, the (ans) sort begins by finding and placing the largest value in element 0

data types

you cannot store a mixture of (ans) in an array

the array must first be sorted in ascending order

In order to do a binary search on an array

fields

The data contained in an object are known as the object's (ans)

New

The key word (ans) creates the object in memory

reference

When using a module to swap the values in two variables, the arguments must be passed into (ans) parameters in the module

subscript

using a loop's counter variable as a (ans) makes it possible to perform the same action on each element in an array

output

the (ans) file is used to describe a file that data is written to
