No. Strings in Java are made of char [] behind the scenes, and char are primitive, and can't be null. Maybe there is a non-printable "null" character that can be created with an escape code though.

Clarification. I should have said the NUL character, the character whose ASCII value is 0.

Yes, I've dealt with reading files containing the null character.
