PPT-Chapter 9 Arrays What is an Array

An array is a special variable which can hold a collection of elements of the same type Examples A list of colors A list of objects such as rain drops or cars A list of players in a game . Rectangular & Jagged. Plus: More 1D traversal. Array. . Recall. Creating a 2D array of doubles:. double[][] grid = new double[3][4]; . 3 rows: indices 0 to 2, 4 columns: indices 0 to 3. grid. : reference to entire array. In high-level languages, we have several . technigues. available for . constucting. data . stuctures. :. One-dimensional arrays. Multi-dimensional arrays. Structs. Bit sets. Linked lists. Trees. e. Dr. Jose Annunziato. Arrays. Up . to this . point we have been working with individual primitive data types. Arrays allow working with multiple instances of data of the same type. Arrays contain (or refer) to several pieces data stored in contiguous memory spaces. Arrays. (Based on . Deitel. . Ch. 8). 1. Collections. Collections are data structures that holds data in different ways for flexible . operations. . C. # . Collection. classes are defined as part of . Objectives. In this chapter, you will learn about:. Arrays. and how they occupy computer memory. Using an array to replace nested decisions. Using . constants. with arrays. Searching. an array. Using . We will often need to store collections of information. a list of names to sort. a list of values to compute averages, standard deviation, . etc. a group of GUI components. Java provides different types of . , Floating Point Numbers. Serialization. Serialization is the concept of turning any data structure or objects into a stream of bytes.. In C, we lack proper objects so most of our data structures are already bytes in memory.. Declaring and Using a One-Dimensional Array. Passing an Array as a Function Argument. Using . const. in Function Prototypes. Using an Array of . struct. or . class. Objects. Chapter 11 Topics. Using an . What is an Array?. Array is a data structure that . holds . a . collection. of . data of the . same . type. . Java . treats . arrays as . objects. . This means array variables are . reference . variables, .
