x = find . -name "*.java" | wc -l
echo $x

This should also work:

x=`find . -name "*.java" | wc -l`

It should be

x=$(find . -name "*.java" | wc -l)

(Note that there is no space around the = sign)

To answer your question, the problem is

  1. the space after x causes the shell to try to execute the command x which probably does not exist

  2. you want the result of the command to be stored in x, so you need to execute the command (hence the $(...))
