What is returned after child.waitFor() execution?
<pre><code>    String command = "javac -cp .:../sqljdbc.jar SetHash.java";
   Process child = Runtime.getRuntime().exec(command);
  try{
  c= child.waitFor();
  } catch (Exception ex){ex.printStackTrace();}
</code></pre>

<p>Hi...
I would like to know which value will be assigned to "c" variable in the above structure if the command runs successfully. Also I would like to know if there will be any change in the value that will be assigned to "c" if the command does end up with an error.</p>
