No, you wouldn't.  That would give you the number of source files - at 
best.  Worst case is an error from "find" indicating invalid command 
line arguments.  Other variants are also possible, e.g. including 
directories or symlinks in the count.

More successful approaches

find src -type f -name \*.java -exec cat {} + | wc -l

{
   echo 0
   find -type f -name \*.java -exec wc -l {} + \
   | sed -n 's#^ *\([0-9]\+\) \+total$#\1+#p'
   echo n
} | dc

Btw, all these also count empty lines.  For non empty lines something 
like this could work

{
   echo 0
   find -type f -name \*.java -exec egrep -hc '[^[:space:]]' {} + \
   | sed 'a +'
   echo n
} | dc

Kind regards
