How to sort an Object[] array based on one of its elements?

Question

I need your assiatance please:

I have a map :

Map<String, Object[]> data = new HashMap<String, Object[]>();

The Object[] array is built out of triples: [String, String, Integer]

Later on, I am going to read the object[] array values, but I should print them sorted according to the integer value.

How can I do this in the best way?

Thank you!

One way is with a stream:

data.values().stream()
    .sorted(Comparator.comparing(a -> (Integer)a[2]))
    .forEachOrdered(a -> System.out.println(Arrays.toString(a)));
