Arrays

What is?

• Data Structure consisting of a collection of elements
• Each is identified by an index
• Numbers call indices
• All data stored in an array must be of the same time
• IMPORTANT!!! When we code the index starts from 0 but on the AP the index starts from 1

Working with Arrays

1. Declare
2. Initialize
3. Load

Syntax

• Declaring

//Declaring:

int [] myArray;

• Initializing

//Initializing;

myArray = new int [10];

• Declaring and Initializing in 1 line

//Declaring and Initializing in 1 line

int [] myArray = new int [10];

• Loading Traditionally

//Loading an Array Traditionally

myArray[0]=10;
myArray[1]=11;

//All at once
int [] myArray = {1,2,3,4,5,6,7};
