Hey everybody I have object which stores multiple integer values. I want it to sort it multiple times by descending order, one time descending by "Wins" value, another time descending by "Played" value etc... How can I do that ?

  • First of all what do you mean with "I hava object which stores..."? Furthermore you should provide the version of Java you use and provide some code snippets. – rufer7 Jan 05 '18 at 12:33

  • In case you want to have a combined order (i.e. order by wins, and order equal wins by played), I find [this answer](https://stackoverflow.com/a/39571813/7653073) more suitable. – Malte Hartwig Jan 05 '18 at 12:37

Here is the sample code for the problem

    public class MyObject  {
        private int wins;
        private int played;         
        // to do add getter and setter method for the above fields
    }

    List<MyObject> objects = new ArrayList<MyObject>();
    // to do java code for creating Myobjects

Before Java 8 :

// wins sorting
objects.sort(new Comparator<MyObject>() {
    @Override
    public int compare(MyObject m1, MyObject m2) {
        return m2.getWins() - m1.getWins();
     }
});

// Played sorting
objects.sort(new Comparator<MyObject>() {
    @Override
    public int compare(MyObject m1, MyObject m2) {
        return m2.getPlayed() - m1.getPlayed();
     }
});

Java 8 Code:

objects.sort(Comparator.comparingInt(MyObject::wins) .reversed());
objects.sort(Comparator.comparingInt(MyObject::played) .reversed());
