title: Error : java.io.IOException: CreateProcess error=193, %1 is not a valid Win32 application
body: <p>I've an error in this code:</p>
  
  <pre><code>    String rollno="13f127";
      String file="code";
      Process p = Runtime.getRuntime().exec("C:\\Users\\Raga\\Documents\\"+rollno+"\\"+file+".py &lt; C:\\Users\\Raga\\Documents\\"+rollno+"\\input.txt");
  </code></pre>
  
  <p>I don't know how to create that process and what's wrong in this line. Please help anyone! </p>
  
  <p>I've seen this type of questions earlier but in my problem, I'm using to compile python program with the input given from the file. So I want to know how this one differs! </p>
