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
