You have a few options for increasing the arrays size: * Make the array have a larger size, leaving some spaces empty * Create a new array of the size you need, then add all the elements of the previous array over to the new array * Use an arrayList * Use a Linked List

you can declare an array like this? int [] i = new int [5]; now you can initalize each element i [0] = 41; System.out.println (i [0]); output 41 or you can cast the int to double inside print method System.out.println (double)i [0])); output 41.0
