Is a named list of data items that all have the same data type.

Array

Data items of an Array.

Element

Is an integer contained within square brackets that specifies one of an array’s elements. They are also called index, which can be seen in error messages in compiler

Subscript

To initialize an array, use an _____________ of values separated by commas and enclose within curly braces

Initialization list

Is called when the programmer provides values to all the elements of the array

Populating the array

The length in array is NOT A METHOD, it is a _________

FIELD or property of the object

A loop that allow the program to iterate though an array without specifying the starting and ending points for the loop control variable

Enhanced for loop

Is one with the same number of elements as another, and for which the values in corresponding elements are related.

Parallel Array

A variable that holds a value as an indicator of whether some condition has been met

Flag

Comparing a value to the endpoints of numerical ranges to find the category in which a value belongs

Range Match

Is the process of arranging a series of objects in some logical order.

Sorting

Is a process or set of steps that solve a problem.

Algorithm

Is a simple sorting algorithm that repeatedly goes through the list, compares adjacent elements and swaps them if they are in the wrong order

Bubble Sort

Is an algorithm that looks at each list element one at a time and if an element is out of order relative to any of the items earlier in the list, you move each earlier item down one position and then insert the tested element

Insertion sort

Mathematicians also use two-dimensional array and they call it ________ or a table.

Matrix

Tech-savvy people often call 2D arrays as ________

Spreadsheet

Declaration: datatype[][] variable = new datatype[x][y]; where x represents the ________

Rows

Declaration: datatype[][] variable = new datatype[x][y]; where y represents the _________

Columns

– a 2D array that has rows of different lengths. It can also be called as non-rectangular array

Jagged array

Arrays with more than one dimension

Multidimensional arrays

Another well-known data structure of Java is the _______

Arraylist

Is a dynamic data structure, where items can be added and removed from the list.

ArrayList

Method to insert elements

Add()

Method to access an item.

Get()

Method to change an item.

Set()

Method to remove an item.

Remove()

Method to get the size of the arraylist

Size()

Is a mechanism that enables one class to acquire all the behaviors and attributes of another class.

Inheritance

Is a visual tool that provides you with an overview of a class.

Class diagram

Is a class that is used as a basis for inheritance.

Base classor superclass or parent class)

Is a class that inherits from a base class

Derived class (or subclass or child class)

The relationship in which a class contains one or more members of another class, when those members would not continue to exist without the object that contains them.

Composition

The relationship in which a class contains one or more members of another class, when those members would continue to exist without the object that contains them

Aggregation

Methods that work appropriately for subclasses of the same parent class

Subtype polymorphism

Lets the compiler know that your intention is to override a method in the parent class rather than create a method with a new signature

Override annotation

Statement must be the first statement in any subclass constructor that uses it.

Super()
