how to check if file is empty

[kristian jarvi]

I want to check if the file I'm trying to
read is empty and exit program if it's empty.
I've tried
if(bis.readLine().length()==0)
System.out.print("File is empty!");
}
else...
and
if(bis.readLine()==null)
System.out.print("File is empty!");
}
else...
but it's not working the way I want.
If i try to read an empty file it doesn't
print out the message i like.

File inputFile = new File ("test.txt");
FileReader fis =new FileReader(inputFile);
BufferedReader bis = new BufferedReader(fis);
for(String line=bis.readLine().trim();line != null;line=bis.readLine()) {

well you can use the function of File class called Length
-------------------------------------------
public long length()
Returns the length of the file denoted by this abstract pathname.
Returns:
The length, in bytes, of the file denoted by this abstract pathname, or 0L if the file does not exist
Throws:
SecurityException - If a security manager exists and its
SecurityManager.checkRead(java.io.FileDescriptor) method denies read access to the file
-----------------------------------------------
now
if(myfile.Length()==0)
//print file empty
let me know if this works
