title: Reading Java system properties from command line
body: <p>Is there a better way to print system properties from command line? As we can set the property e.g. </p>
  
  <pre><code> java  -D&lt;name&gt;=&lt;value&gt;  //set a system property
  </code></pre>
  
  <p>Without writing a class to do that? </p>
  
  <p>If not possible, why is it not possible/feasible/good to do that from the command line ?</p>
