Checking empty string in an arraylist

Question

The arraylist that i am working on.

[Bibek Gurung, 9.808112115E9,  , [email protected]]

The code I've tried to check the empty index in an array:

if (!singleRecordExtract.get(2).toString().isEmpty()) {
 //but it passes through the validation
}

I've tried this but somehow, the validation is not working. And I wonder how? Does anyone know the solution or a work around for this problem?

Because this array list is extracted from excel file and I want to set the values to the object of the Class that i want. In order to do so, I am checking for the empty fields. — Akash Rajbanshi

The string in the list is probably " ". isEmpty returns false for strings with whitespace. You can fix this by using trim() which removes whitespace from the front and back of a string. This will make your string actually empty.
