Example 1 with IntSet

use of org.eclipse.collections.api.set.primitive.IntSet in project eclipse-collections by eclipse.

the class PersonAndPetKataTest method getAgeStatisticsOfPets.

@Test

    IntList ages = this.people.asLazy().flatCollect(Person::getPets).collectInt(Pet::getAge).toList();
    IntSet uniqueAges = ages.toSet();

    Assert.assertEquals(IntHashSet.newSetWith(1, 2, 3, 4), uniqueAges);
    Assert.assertEquals(stats.getMin(), ages.min());
    Assert.assertEquals(stats.getMax(), ages.max());
    Assert.assertEquals(stats.getSum(), ages.sum());
    Assert.assertEquals(stats.getAverage(), ages.average(), 0.0);
    Assert.assertEquals(stats.getCount(), ages.size());
    Assert.assertTrue(ages.allSatisfy(IntPredicates.greaterThan(0)));
