Java – is the first element of an array returned using split always safe?

I'm sure the answer is yes, but I just want to make sure that no non empty string (whatever it contains) will return anything except a valid string as the first member of the returned array Split

Put it another way

String foo = ""; // or "something" or "a b c" or any valid string at all

String[] bar = foo.split(",")[0];

My understanding is that bar will never be null and the assignment line cannot fail If no delimiter is found in the string, it returns only foo as the first element of the returned array

Solution

No, it may fail

If foo =, ", it cannot pass arrayindexoutofbound
