String[] array2 = new String[5] //String array length 5
double[] array3 = new double[5] // Double array length 5

int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }

String[][] arrays = new String[][] { array1, array2, array3, array4, array5 };

(file name) file name(s) = new (File name)[/*amount*/]
  
  void setup() {
  	for (int i = 0; i < (file name(s)).length; i++) {
