title: Should we keep 80 characters per line in Java?
body: <p>There are lots of websites or blogs said that we should keep 80 characters per line in our program since it is relatively to display in some console environment.</p>
  
  <p>However, I found that it is very hard to keep this practice in Java. When we write Java code, we write a function in a class, it requires us to do some indentation already, let alone to add a few if-else statements inside the function.</p>
  
  <p>Apart from that, we always keep call functions in a object. Such kind of behavior make that it is hard to make 80 characters per line.</p>
  
  <p>Wrapping the line is a method, but it decrease the readability of the code.</p>
  
  <p>I am not a professional java programmer. Would you still follow this rule  when writing Java? or is there common practice on the indentation of java?</p>
