title: java difference StdOut vs System.out.println
body: <p>I have just started working on java, As i downloaded the eclipse and created a java project. 
  Project was working fine, then i imported a class but it's not working due to following lines</p>
  
  <pre><code>StdOut.println(p + "  " + q);
  </code></pre>
  
  <p>after searching i have replaced it with </p>
  
  <pre><code>System.out.println(p + "  " + q);
  </code></pre>
  
  <p>and same way for input. </p>
  
  <p>I tried importing <code>system.io.*</code> didn't worked. then i tried <code>import StdIn</code> not worked</p>
  
  <p>As i can feel is that it may be due to different project template/type. and tutorials links will also be helpful. Thanks</p>
