title: Java runtime exec
body: <p>I am trying to do something using system exec in Java</p>
  
  <pre><code>Runtime.getRuntime().exec(command);
  </code></pre>
  
  <p>Surprisingly everything that is related with paths, directories and files is not working well</p>
  
  <p>I don't get why and just want to know is there any <strong>alternatives</strong>?</p>
