How to check if a file is empty?

Hi Masters.....
I have problem !!!
I need to check number of records in a file and if it is zero or file is empty i need to do some task.
if [Zero record]; then
echo "File s empty"
else
echo "Not empty"
fi
so how to check this condition.
I used wc -l < filename.txt => 1 for zero records
same result with- awk '{n++}' END '{print n}' filename.txt

if [ ! -s file ] => this condition is also not working out.
Can any one help me out in this please....

Code:

[[ -s "file" ]] && echo "Filesize not zero" || echo "Filesize zero"
