title: What is the difference between void method and return this
body: <pre><code>Class Player {
  Player setName(String name){
  this.name = name;
  return this;
  
  // or
  
  void setName(String name){
  this.name = name;
  }}
  </code></pre>
  
  <p>Hi. What is the difference if I use the method with "void" or "return this" statement? Why the "return this" statement exists, if it does the same?</p>
