//Arrays - a list of variables with a name and index number for each element
//A few examples

//declare an array
int[] numbers = new int [3];
//initialize elements of the array one at a time
numbers[0] = 90;
numbers[1] = 150;
numbers[2] = 30;

//OR
//declare an array
int[] numbers = new int [3];
//initialize elements of the array in one line
int[] numbers = {10, 24, 5};

//Arrays may be intergers, floating point numbers, expressions, variables, objects

//declare an array
float[] numbers = new float[100];
//initialize elements of the array using while loop
while (i < 100) {
  numbers[i] = 1;
  i = i + 1;
}

//declare an array
float[] numbers = new float[100];
//initialize elements of the array using for loop
for (float i = 0; i < 100; i++) {
  numbers[i] = 1;
}

//The size of an array may be based on a variable.
//Processing provides the keyword "length" to access the size of an array
//arrayName.length:

for (int i = 0; i< values.length; i++) {
  values[i] = random(0,10);
