Accidently splitting an empty string on some specific character returns a list of size One
Why splitting of empty string on some specific character returns a list of size One? What does this list contain if it has size One?
Sample code:`string s='';
list<string> str = s.split(',');
if(str.isEmpty()){
system.debug('Hello i am empty');
}
else{
system.debug('oops');

The property of split() is such that the list you get back always has at least one element. You are splitting the empty string, and so you're getting back a list of size 1, where the element in the list is the empty string.

Splitting an empty string returns the empty string as the first element. If no delimiter is found in the target string, you will get an array of size 1 that is holding the original string, even if it is empty
Example:
String str =",Utsav"
str.split(',') will return a list of size 2If you split an orange zero times, you have exactly one piece - the orange

Split always returns at least one element.
In the case that a separator is not found, the entire input (empty String) is returned as a single-element in the List. For that reason the List size will be always one.
