Description Mirko Novakovic CLA 2004-06-01 10:03:16 EDT 
Using the following code, I get an "Local vaiable is never used" warning.

String zeile = null;
while ((zeile = copystrecke.readLine()) != null) {
         ...
}

It seems that the assignment in the while statement is not evaluated for this 
warning.

Are you using the variable zeile in the while block?
Comment 2 Philipe Mulet CLA 2004-06-01 11:31:03 EDT 
The warning says: "Local variable is never *read*". An assignment is only a 
write access.
