title: The use of "ln" in System.out.print("");?
body: <p>I'm doing an intro course in Java and I just wanted to know, because my professor isn't very smart, what the difference between:</p>
  
  <p><code>System.out.print("Hello World!");</code></p>
  
  <p>and </p>
  
  <p><code>System.out.println("Hello World!");</code></p>
  
  <p>He said it's something about a new line but he doesn't explain very well so ... Thanks!</p>
