Sort a List of Java objects

Sort with Collections.sort () using Comparator

--Comparator allows you to sort by a specific value of your own class object.


//List<Person>Sort the list foo by x field
                  new Comparator<Person>() {
                    public int compare(Person obj1, Person obj2){
                      return obj2.getX - obj1.getX;

Use Comparator.comparing

--Comparator.comparing allows you to write neatly
