title: How to compile and execute this JAVA application in Ubuntu?
body: <p><img src="https://i.stack.imgur.com/y4QcU.png" alt="This is my folder structure of my java project"></p>
  
  <p>There is a Hdfs.java inside <em>src/hdfs</em> and there is a utility jar file inside <em>lib</em>.</p>
  
  <p>What are the options I give when I compile the Hdfs.java using the utility jar?
  And how do I execute?</p>
  
  <p>I went through the examples <a href="http://manpages.ubuntu.com/manpages/hardy/man1/icepick-javac.1.html" rel="nofollow noreferrer">here</a> and I'm very confused.</p>
