String cmbList[] =new String[1];

when creating the array it is 1 based, so what you are doing is creating an empty array with no elements

ArrayIndexOutOfBounds means that you are trying to access an array elements that does not exist:

Picturs this.

String arr[] = new String[3];

this would look something like this

["", "", ""]

So when you do

String srr[] = new String[0];

you get this:

[]  << see no elements


When access array elements it is 0 based, 0 is the first element in the array, but if you have no elements in the array, there is nothing to access!
