title: How can I print line side by side in Java?
body: <p>I couldn't find this anywhere; I might finding it with the wrong keywords.</p>
  
  <p>Pictures paint a thousand words, so let me explain.</p>
  
  <p>Supposed we have a set of unknown number of String:</p>
  
  <pre><code>String hello = "Hello world\n Welcome\n"
  String goodbye = "Goodbye\n See you in the next life\n"
  String do = "Do something\n Be part of us\n"
  </code></pre>
  
  <p>I would like a function that produce such result:</p>
  
  <pre><code>String hellogoodbyedo = "
    Hello world_________________Goodbye________________________Do Something\n
    Welcome_____________________See you in the next life_______Be part of us\n"
  </code></pre>
  
  <p>In which <em>_</em> means spaces. Is there a smart way of doing such?</p>
