so basically putting -1 in length attribute will cause the loop to find the end of a certain value? Did I get it right, by the thanks for the reply it help me a lot.

Answer 3

The array.length property gives you the elements's count in the array. But as we know, indexes of the elements starts from 0. So the last element is at index array.length - 1.

Using for-loop:
for (int i = 0; i < array.length; i++) {}

Or for-each loop:
for (String day : days) {}

Answer 4

i<data's.length

Answer 5

days.length();
