title: How do I make 2 comparable methods in only one class?
body: <p>I've got one class, that I sort it already by one attribute.
  Now I need to make another thing, that I need to create another way to sort my data.
  How can I make it, so I can choose between the two methods.
  The only command I know is Collections.sort that will pick up the method compareTo from the class I want to compare its data.</p>
  
  <p>Is it even possible?</p>
