Usage

From source file:Main.java

public static void main(String[] args) {
    // setup//from   ww  w .j  av  a2 s. c om
    List<Integer> list = new ArrayList<Integer>();
    list.add(4);
    list.add(3);

    // classic way
    list.sort(new Comparator<Integer>() {

        @Override
        public int compare(Integer a, Integer b) {
            return a - b;
        }
    });
    System.out.println(list);

    // lambda way, the shortest way
    list.sort((a, b) -> a - b);
    System.out.println(list);

}

From source file:Card.java

public static void main(String args[]) {
    List<Card> lc = new ArrayList<Card>();
    lc.add(new Card(Card.Rank.SIX, Card.Suit.CLUBS));
    lc.add(new Card(Card.Rank.TEN, Card.Suit.CLUBS));
    lc.add(new Card(Card.Rank.SIX, Card.Suit.HEARTS));
    lc.add(new Card(Card.Rank.ACE, Card.Suit.HEARTS));

    System.out.println(lc);//from  w ww . j  av a2  s .  co  m
    Collections.sort(lc);
    System.out.println(lc);
}
