Examples  
int[] numbers = new int[3]; 
numbers[0] = 90; 
numbers[1] = 150; 
numbers[2] = 30; 
int a = numbers[0] + numbers[1]; // Sets variable a to 240 
int b = numbers[1] + numbers[2]; // Sets variable b to 180 


int[] numbers = { 90, 150, 30 }; 
int a = numbers[0] + numbers[1]; // Sets variable a to 240 
int b = numbers[1] + numbers[2]; // Sets variable b to 180 


int degrees = 360; 
float[] cos_vals = new float[degrees]; 
for(int i=0; i < degrees; i++) { 
  cos_vals[i] = cos(TWO_PI/degrees * i); 
} 

Description   An array is a list of data. It is possible to have an array of any type of data. Each piece of data in an array is identified by an index number representing its position in the array. The first element in the array is [0], the second element is [1], and so on. Arrays are similar to objects, so they must be created with the keyword new. Every array has a variable length which is an integer value for the total number of elements in the array.
   
Syntax  
datatype[] var
var[element] = value
var.length
   
Parameters  
datatype   any primitive or compound datatype, including user defined classes

var   any valid variable name

element   int: must not exceed the length of the array - 1

value   data to assign to the array element, must be the same datatype as the array
