Just curious why a new Array String [0] wont work?

Question

/*i know it will work with another number but i thought [0] is an array number. thanks*/

public class Program {

static void println(String y){System.out.println(y);}

public static void main(String[] args) {

String [ ] x = new String[0];

x[0] = "Hello";

println(x[0]);

x[0] = "World";

println(x[0]);

}
}

Answer 1

it is of zero size. (no elements) i think you mean to say string[1]

Answer 3

the 0 used with x is a reference to the first element of the array.

the 0 you have used with string declares the number of elements in the array

Answer 4

ah so new string [1] < is referenced as element [0] in the array 😉 thanks

Answer 5

@jay, even with "new String [1]"it still throws an error i need at least "new String [2]" for some reason and i can create as many arrays as i want??.

i thought 0 was 1 array it seems like that in a single array.

if im assigning only 1 declared array i dont understand why i need 2 or would that be 3 lol.
